Working principle
A pump casing contains a special high elasticity and
resistance hose, which is flanged at both ends (connections).
The flanges are connected to the suction and
discharge lines of the system.
Within the casing is a rotor with two rollers at
opposite points about its centre line and mounted
on a shaft with bearings.
As a result of the rotor pivoting, the hose is totally
compressed by the rollers and the product within
the hose is pushed forward.
The sucking action comes as the hose restores its
original cylindrical form after compression.
The hose's worn surface must be lubricated with
siliconic grease.

Features
Highly suitable for:
- abrasive products
- corrosive products
- shear sensitive products
- viscous products
- high density products
- metering purposes
- vacuum situations
- use in explosive environments
Self priming
Can run dry, therefore can work with out fluid
   continuously
Reversible rotation.
Hose replacement without dismantling the pump.
Easy to clean and sterilize.
The pumped fluid doesn't contact any mechanical part.
Simply adjustable.
The hose is the only wearing part.
Easy maintenance, low cost, short down time.
Hose lubrication with siliconic grease.
