Pump system for pastes and high
viscosity products
Transferring very high viscosity creams, gels and pastes which do not flow used to present a major problem for companies in the food, cosmetics, pharmaceutical and process industries
Transferring very high viscosity creams, gels and pastes which do not flow presents a major problem for companies in the food, cosmetics, pharmaceutical and process industries: now the CSF pump system provides the answer Liquids handling specialists Pump Engineering offer the solution with a CSF piston pump, already widely used for high viscosity fluids in these industries, fitted to a twin ram system which enables the pump to be used for these problem products

Portable gear pump for viscous fluids
The GVR range of self-priming, external gear pumps is ideal for transferring viscous fluids such as lubricating and hydraulic oils which require a robust, reliable, yet competitively priced pump
Tough seal-less pumps unaffected by dry-running
ASV seal-less eccentric pumps from Pump Engineering are suitable for many fluids transfer applications, whilst providing a tough and durable performance with minimal maintenance requirements
The system works by using a short CSF piston pump mounted in the centre of a follower plate, which fits into a drum and seals against the inside of the drum.
Two pneumatic cylinders force the plate onto the top of the product.
As the pump empties the drum, so the plate is pushed downwards, keeping the inlet of the pump full of the product.
A rubber seal on the follower plate wipes the side of the drum as it travels downwards, sealing it and ensuring that very little product is wasted.
The pumps are available as quick strip versions for easy cleaning without the need for tools.
The system provides a solution to products as diverse as peanut butter, petroleum jelly, inks, yeast extract and mascara.
For lower viscosity liquids, a long version of the pump is available for emptying tanks drums and IBCs, with a special bag-in-drum inlet, which prevents the plastic drum lining used in some industries, being drawn into the pump.
CSF pumps are air operated and depending on the model, will deliver flowrates up to 100 litres/minute with pressures up to 100 bar.
Materials of construction are AISI 304, or 316 stainless steel with Viton, nitrile or PTFE seals.
