Features and benefits of peristaltic pumps

Peristaltic pumps provide excellent and reliable pumping solutions especially for the products which are particularly abrasive, corrosive or highly viscous. With no valves, seals and glands, peristaltic pumps are inexpensive to maintain. The only maintenance item is the hose or tube which has a long life depending upon your pumping action. Gentle pumping action makes them ideal for shear sensitive polymers and fragile cell cultures. Peristaltic pumps only part in contact with the fluid is the internal tube or hose, this makes them easy to sterilise and to clean the inside surfaces of the pump.

Seal-less design

Peristaltic pumps are seal-less which eliminates the leakage threat of corrosive chemicals and ongoing maintenance.

Low maintenance costs

Hose or tube are the only replacement part in a peristaltic pumps. Both are relatively low cost item and can be replaced in a short time.

Dry running and self-priming

Peristaltic pumps fluid to be running continuously, they have the ability to run dry, without repairs or downtime. Recovery of hose or tube creates powerful self-priming action and allows the pumps to move liquids containing entrapped air.

Gentle pumping action

Peristaltic pumps have a gentle, low shear pumping action, ideal for shear sensitive products including flocculants and broths

High suction lift

The powerful suction provided by the recovery of a re-enforced hose gives hose pumps suction lift capabilities up to 9.5m of water.

Abrasion resistant

Hose life is not related to a product’s abrasive qualities. The hose only fails due to fatigue or chemical action.

Solids handling

Verderflex hose pumps can pump slurries containing up to 80% inorganic solids or 15% organic sludge.

Reversible

Peristaltic pumps are reversible and can be used to empty lines or clear blockages

No slip

The pumps have no internal backflow giving accurate dosing without slip

Accurate dosing

The pumps are accurate in dosing; they have a repeatability of ±1% and metering capabilities of ±5%.

Hygienic

The VF flange is certified to EHEDG standards for use in the food, beverages and pharmaceutical industry, plus other sanitary related applications.
