AS Peristaltic Pumps

Operation Principle

A pump casing contains a high-elasticity hose, which is flanged at both ends. The flanges are connected to the suction and discharge lines of the system. Within the casing there is a rotor with two rollers at opposite sides. As a the rotor is rotating, the hose is totally compressed by the rollers, and the product within the hose is pushed forward. The sucking action starts as the hose restores its original cylindrical form after compression. The hose's surface must be lubricated with siliconic grease.

The advantage of AS hose pumps is that the only pump part contacting with medium is a hose. Such design eliminates pump seal using. Hose surface should be lubricated by a silicon grease.

• Process pressure — up to 3 bar;
• Flow rate — up to 2.5 m³/h;
• Self-priming, head up to 9.5 m;
• Dru run is available;
• Reversive rotation is available; 
• Hose replacing without pump dismantling;
• Easy cleaning and sterilizing;
• Pumped liquid does not contact with mechanical parts;
• Easy adjusting;
• The hose is the only wearing part;
• Easy maintainance, low cost and short downtime;
• Do not require expensive auxiliary equipment: design does not include mechanical seals, ball valves,diaphragms, gland seals, submersible rotors, stators and plungers which can leack, become fouled or get rusted;
• Hose should be lubricated by silicon grease;
• Easy operation and maintenance;
• Prevents leackages, pump equal volumes per rotation.
