High shear pumps may also cause the lubricant to froth or foam. It is important the pump does not degrade or change the lubricant properties. Pumps should be designed to work with water-based materials. While piston-style grease pumps work for a while, unless they are coated steel, stainless, aluminum, or non-metallic, they eventually corrode from the water-base materials. Suitable pumps are found in the chemical, food processing, agricultural, sewage, marine and medical industries.<\/p>\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\n<tbody>\n<tr>\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/products\/lubricants\/?industry=lubricants\" target=\"_blank\" rel=\"noopener\">Unsure if you have the right lubricant for the job? <strong>Click here to explore Polywater&#8217;s lubricants.<\/strong><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>What kind of power source is needed and available for my pumping system?<\/h2>\n<p>Since most cable installation sites are remote, it is important to consider how the pump will be powered. There are pumping options that utilize air power (compressor driven), battery power (12 or 18 volt or rechargeable), and electric power. The choice of power source is a balance between what is needed and what is available. Pumping at a higher rate for further distances requires more power.<\/p>\n<h2>How much pumping capacity do I need?<\/h2>\n<p>The pumping capacity consideration can be broken into two parts:<\/p>\n<ul>\n<li>Pumping Rate: The amount of lubricant needed per time increment.<\/li>\n<li>Pumping Power: The distance the lubricant must travel through the hose and the effort it will take to move it there.<\/li>\n<\/ul>\n<p>The pumping rate is a critical component to determine capacity requirements.

The calculation requires the installer to know how much lubricant is needed as well as how fast the cable is traveling. The lubricant quantity is directly related to the surface area to be coated with lubricant and can be found using the lubricant quantity formula:<\/p>\n<p><strong>Equation 1<\/strong><\/p>\n<p>Q = K x L x D<\/p>\n<p>Where:<\/p>\n<p>Q = quantity in gallons (liters)<\/p>\n<p>K = conversion factor, 0.0015 (0.0008 metric)<\/p>\n<p>L = length of duct run in feet (meters)<\/p>\n<p>D = ID (inner diameter) of the duct in inches (mm)<\/p>\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\n<tbody>\n<tr>\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/product-resources\/calculators\/lubricant-quantity-calculation\/\" target=\"_blank\" rel=\"noopener\">Polywater can help determine the amount of lubricant needed for any job. <strong>Click here to try our lubricant calculator.<\/strong><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The bigger the duct system, the more lubricant is needed. If you go from 4 inches (100 mm) to 8 inches (200 mm), the quantity requirement will double. For more difficult installations, <a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/the-science-of-cable-lubrication-film-thickness-and-quantity-recommendations\/\" target=\"_blank\" rel=\"noopener\">prelubrication is recommended<\/a>. Any lubricant added and spread through the duct ahead of the cable pull is part of the lubricant quantity recommendation. Pumps can be used to inject lubricant into the pump ahead of lubricant spreaders. In this case, the pumping rate is less important.<\/p>\n<p>If the conduit is prelubricated, the amount of lubricant used can be subtracted from the quantity calculated using the quantity formula. The remaining lubricant is coated onto the moving cable as it enters the conduit. This means that cable speed is an important part of the pumping rate calculation. A cable moving 70 feet\/minute (20 meters\/minute) requires twice as much lubricant per minute as that of a cable moving 35 feet\/minute (10 meters\/minute). See Equation 2.<\/p>\n<p><strong>Equation 2<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-30047\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Pumping-Rate-Equation-Graphic.png\" alt=\"Equation for Pumping Rate Based on Duct Size &amp; Pull Rate\" width=\"200\" height=\"47\" \/><\/p>\n<p>Where:<\/p>\n<p>Pumping Rate is in gallons per minute (liters per minute)<\/p>\n<blockquote><p>Q = lubricant quantity in gallons (liters) from Equation 1<\/p>\n<p>QP = quantity of lubricant used to prelubricate duct<\/p>\n<p>L = length of duct run in feet (meters)<\/p>\n<p>R = rate of installation in feet per minute (meters\/min.)<\/p><\/blockquote>\n<p>The key factors determining pumping rate are duct size and cable installation speed. Note that the length of the run does not impact pumping rate. The length of the run is used to calculate the total quantity of lubricant needed. The length is then divided out of the formula to determine pumping rate. Graph 1 illustrates some examples of pumping rate.<\/p>\n<p><strong>Graph 1: Pumping Rate Based on Duct Size and Pull Rate<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-24134\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Pumping-Rate-Based-on-Duct-Size-Pull-Rate-Graph.jpg\" alt=\"\" width=\"934\" height=\"575\" \/><\/p>\n<p>Note that the pumping rate for the 4-inch (100 mm) duct is half of that required for the 8-inch (200 mm) duct. It is a linear relationship. Note that the lubricant quantity needed when pulling at 35 feet\/minute is half that required for a pull rate of 70 feet\/minute. This is also a linear relationship.<\/p>\n<table style=\"width: 100%; border: 3px solid #273A80; background-color: #69c3e8; margin: 15px 0px 15px 0px;\">\n<tbody>\n<tr>\n<td style=\"padding: 20px; text-align: center;\"><a href=\"https:\/\/www.polywater.com\/en\/knowledge-hub\/how-prelubrication-increases-the-odds-of-a-successful-cable-pull\/\" target=\"_blank\" rel=\"noopener\"><strong>Related Content: <\/strong>How Prelubrication Increases the Odds of a Successful Cable Pull<\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The cable installation samples in Graph 1 were not prelubricated. Best practices dictate that half of the recommended lubricant quantity is used to prelubricate the duct. If half of the lubricant is pumped into the duct and spread ahead of the cable, only half of the total lubricant quantity will be coated on the cable as it enters the duct. In this case, the pumping rate is also reduced by half.<\/p>\n<p>Table 1 shown below illustrates these samples another way:<\/p>\n<p><strong>Table 1<\/strong><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29952\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Table-1-Pumping-rates.jpg\" alt=\"A chart that describes the pumping rate of lubricant based on the cable pulling rate, conduit size, and whether the conduit is prelubricated.\" width=\"900\" height=\"363\" srcset=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Table-1-Pumping-rates.jpg 900w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Table-1-Pumping-rates-300x121.jpg 300w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Table-1-Pumping-rates-768x310.jpg 768w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><\/p>\n<p>The pumping rate varies based on the size of the system and the rate of the cable pull. The pump and power requirements for the large installation are different than the requirements for a more standard installation. Generally, the pumping rates required for cable lubrication are low. It is important to look for a steady or consistent flow rate. High flow rates are not required.<\/p>\n<h2>Pumping Capacity and Lubricant Viscosity<\/h2>\n<p>Pumping capacity may be influenced by both the lubricant viscosity and the distance \u2013 both horizontal and vertical \u2013 it must travel. Cable pulling lubricants come as slightly thickened liquids as well as thick gels. Moving viscous lubricant through the dispensing hose may create back pressure and, in turn, require more power.<\/p>\n<h2>Polywater\u2019s Experience<\/h2>\n<p>Polywater has experience with various pumping technologies and real field solutions. We have discussed the need for the pump to be compatible with cable lubricants, the power source, and pumping rate. Other pump characteristics to consider include:<\/p>\n<ul>\n<li>Weight and durability<\/li>\n<li>Ease of maintenance<\/li>\n<li>Self-priming<\/li>\n<li>Pumping rate adjustment<\/li>\n<\/ul>\n<p>There are several pump types available for use, including:<\/p>\n<h3>Diaphragm Pump<\/h3>\n<p>Air-powered diaphragm pumps have been used to transfer lubricant from a tote container to a smaller vessel or directly pump lubricant to a cable pull in the field. They are used at Polywater to transfer lubricants around the plant. Diaphragm pumps use air pressure to push an elastic diaphragm that moves the lubricant.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29755\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Diaphragm_PumpingArticle.png\" alt=\"Illustration of a diaphragm pump\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Diaphragm_PumpingArticle.png 300w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Diaphragm_PumpingArticle-150x150.png 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><br \/>\nDiaphragm pumps are a good choice for water-based cable lubricants. Choose a diaphragm pump with compatible housing and diaphragms for water-based materials. They require a relatively low volume of air. Typical air pressure is around 60 psi (4.1 bar). For pumping cable lubricants, an air regulator may be needed to limit and control flow. There is some inherent pulsing in a diaphragm pump, and the pump should be sized to allow sufficient cycling for a reasonably smooth feed at the flow rates desired. As a mechanical pump, some maintenance is necessary, and diaphragms may wear out, requiring replacement. Otherwise, these pumps can last for years.<\/p>\n<p>An automated lubricant system utilizing this type of pump has been used by some large utilities in the Southwest United States. Lubricant is pumped from a tote or tank to the conduit through a flexible hose. The lubricant rate can be controlled by varying the air pressure. In this design, a trigger-grip nozzle controls the lubricant delivery, like a gasoline pump.<\/p>\n<h3>Grease (Piston) Pump<\/h3>\n<p>Grease pumps utilize air pressure and can move highly viscous materials. These are very powerful pumps that can move material at a high flow rate. Because these pumps are intended for hydrocarbon greases, they are susceptible to corrosion when used with water-based cable lubricants.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29750\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Grease-Pump_PumpingArticle.png\" alt=\"Illustration of a grease piston pump\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Grease-Pump_PumpingArticle.png 300w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Grease-Pump_PumpingArticle-150x150.png 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<h3>Polywater LP-D5 Drill-Operated Gear Pump<\/h3>\n<p>The LP-D5 is an economical and convenient pumping system available from Polywater. The pump utilizes a \u00bd-inch (13 mm) drill operating at a speed of 1000 to 2000 rpm. This pump works with a 1-gallon (3.8 L) pail, 5-gallon (19 L) pail, and 55-gallon (209 L) drum using the drum extension. Its copper, brass, and stainless-steel construction makes it corrosion resistant, and its simple design makes it durable. It pumps at a rate of 0.5 to 2.5 gallons (2-10 Liters) per minute.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29745\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/LPD5_PumpingArticle.png\" alt=\"An illustration of a Polywater LP-D5 drill-powered pump.\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/LPD5_PumpingArticle.png 300w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/LPD5_PumpingArticle-150x150.png 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<h3>Battery (Oil and Coolant) Pump<\/h3>\n<p>Pumps powered by a rechargeable 18-volt lithium-ion battery will work in many installations. The appeal of this type of pump is its ease of use and light-weight design. These pumps are typically designed for coolants, oils, and greases. For higher viscosity materials, the pumping rate is limited to \u00bd-gallon (2 L) per minute.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29730\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Battery-Pump_PumpingArticle.png\" alt=\"Illustration of a battery powered pump with a motor on top of a long pipe.\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Battery-Pump_PumpingArticle.png 300w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Battery-Pump_PumpingArticle-150x150.png 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<h3>Pressure Sprayer<\/h3>\n<p>For thin cable lubricants, it is possible to use a concrete sprayer or similar pressurized system to dispense lubricants. This type of pump requires only manual power. In this design the lubricant is transferred to the pump body and the system is pressurized by hand. The pump body is typically limited in volume and both the flow rate and pressure decrease as the lubricant volume drops. Gelled lubricants dispense in a stream pattern even when using a spray system.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-29740\" src=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Sprayer_PumpingArticle.png\" alt=\"Illustration of a pump sprayer including a reservoir for liquid, a hand pump on top, and a hose with a spray attachment.\" width=\"300\" height=\"300\" srcset=\"https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Sprayer_PumpingArticle.png 300w, https:\/\/www.polywater.com\/wp-content\/uploads\/2024\/05\/Sprayer_PumpingArticle-150x150.png 150w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/p>\n<h3>Stick (Water) Pump<\/h3>\n<p>Many utilities have this type of pump on hand for removing water from vaults and utility boxes.
