ELRO Peristaltic Pumps, Series IP
ELRO® peristaltic pumps series IP are designed for the reliable, stationary application in the industrial field. They feature neither valves nor product wetted shaft seals.

The medium to be transferred comes in contact only with the hoses inside. These pumps are especially suitable for the discharge of abrasive, long-fiber or aggressive media as well as fluids of high viscosity or shearing sensitivity. The patented “hose in hose vacuum system” yields numerous technical and economic advantages. The pumps are dry self-priming up to a suction head of 9.5 m (374”). Owing to the integrated vacuum system they feature a constant flow rate.

The early warning system warns of a hose defect possibly arising from normal wear. The pump bodies are filled with special glycerine or silicone for heat dissipation. An infinitely variable control of the flow rate is made possible by implementing frequency-converter controlled motors or mechanical control gear motors.

Suitable for difficult media, e.g. viscous slurries, abrasive materials, fibers and other solids as well as liquid and gas mixtures.
· Without any valves and product wetted shaft seals.
· Dry self-priming up to a suction head of 9.5 m (374”).
· Suitable for shear-sensitive media.
· Flow rates of up to 28m3/h (7398 US gal/h).
· Good dosing performance, easy in-line cleaning.
· Dry-running resistant over short periods of time.
· Warning of hose defects by the integrated early warning system.

ELRO Peristaltic Pumps, Series IP
Operation of Series IP

The rotor rotates within the pump housing filled with lubricant and compresses the pumping hose with the sliding shoe. This process generates a hermetic separation between suction and discharge side.

Once the second sliding shoe compresses the hose, a completely enclosed pumping chamber is formed. This volume corresponds exactly to half the pump capa­city per rotation. A vacuum is also generated inside the pump housing, supporting the elasticity of the hose allowing restoration to its original full cross-section.

The rotation of the rotor forces the pumped medium inside the hose towards the outlet port on the discharge side. During each opening of the hose a vacuum is created on the suction side ensuring constant suction. It also takes place when the hose is empty giving high suction conditions. With each rotation the pumping chamber is reformed and the suction capability is renewed.
