Transfer Pump Selection Made Simple

With a Grunfeld pump system you can be assured of getting reliable equipment with minium effort on your part.

The four factors that need to be taken into consideration are as follows:

Type of Fluid, Viscosity or Thickness, Required Flow Rate, Required Output Pressure.

Knowing fluid viscosity and flow rates makes it easier to find the right pump for your application. However, if you’re not sure then give us a call and one of the team will be

happy to advise you.

Pumping FundamentalsThe versatility of piston pumps is unmatched as they are used in a seemingly endless array of applications and pumping solutions. With this in mind, it is important to remember these basic pumping fundamentals to help ensure the right product is selected for your unique application.

Piston Pump Applications

Piston pumps are used in a wide variety of fluid handling applications. The majority of these can be broken down into four different categories:

Transfer

Moving a low-to-medium viscosity fluid from one location to another. 2-ball and 4-ball style pumps are the most frequently used in transfer applications.

Extrusion

Involves using a piston pump to apply medium-to-high viscosity materials. Typical extrusion applications require accessories like rams and fluid regulators to meet customer requirements. Chop-check and 2-ball pumps are used in extrusion applications.

Coating

This involves application of material by either spray or dipping. Coating applications use 2-ball and 4-ball pumps.

Measuring/Dispense

Measuring and dispense involves the delivery of a specified quantity of fluid on a repetitive basis. Measuring and dispense applications use 2-ball, 4-ball and chop-check pumps.

Ratio

Ratio is the effective area differential between the air motor piston and the lower end plunger rod. An 11:1 ratio indicates the pump air motor piston has 11 times the effective area of the fluid handling piston.

Higher ratio pumps produce higher fluid pressures which allows them to either move higher viscosity fluids or transfer fluids longer distances.

AAt 100 psi of inlet pressure, an 11:1 pump produces 1,100 psi of fluid outlet pressure.

BA 23:1 pump wouldproduce 2,300 psi of fluid outlet pressure, given the same air inlet .

Materials of ConstructionPump components are constructed of different materials to ensure the pump is best suited for a particular application.

Lower Pump End Component Options

Stainless Steel – Used with corrosive fluids and water-borne materials. Stainless steel is corrosion resistant. It can be heat-treated, hard chrome-plated or Ultra-Coated to improve abrasion resistance.

Carbon Steel – Provides excellent abrasion resistance. It can be heat-treated or hard chrome plated. Not suited for water-borne fluids and corrosive materials, as it will rust and deteriorate.

Packing Seal Options

Packing seals are used to seal movement of the plunger rod, both in the throat seal and piston seal areas of the pump. They are made of different materials to ensure chemical and material compatibility to maximize service life.

UHMW-PE (Ultra-High Molecular Weight Polyethylene) – An all-purpose packing material that provides excellent abrasion resistance. Commonly used with inks, acids, and some solvents.PTFE Compatible with all fluids. Provides excellent corrosion resistance but minimal abrasion resistance. Commonly used with corrosive chemicals, ketone, acids, and room-temperature vulcanizing (RTV) materials.PU Particularly suited to waterbased sealants and mastics offering excellent seal life and very high abrasion resistance. High resistance to mineral oils, suitable for lubrication pumps.

Staggered Combining packing seals made of different material combinations can often maximize service life by utilizing the strengths of both materials.

AFR’sAFR’s (Air Flow Regulators) control pump flow minimising pulsation as the pump reciprocates.

For operators applying adhesives and sealants, a continuous flow of product is essential for effective application. The correct AFR will ensure a pulsation free output.

Again chemical and material compatibility must be specified for correct operation.

Material FiltersMaterial Filters prevent foreign bodies from entering dispense guns and valves, essential for ensuring correct operation. With a choice of filter housing materials and different screen sizes, your end of line equipment will be protected.
