Coaxial Flexible Impeller Pump

The coaxial flexible impeller pump is a self-priming positive displacement pump with low rotation speed, particularly suitable for transferring liquids that are dense and/or contain suspended solids.

The pump is equipped with a flexible rubber impeller that transfers the liquid continuously without altering its characteristics.

It is widely used for transferring wine, must (even with grape residues), and in general in the food and beverage sector, especially for beer, fruit juices, milk and yogurt. It is also commonly used in the oil industry and in the chemical and pharmaceutical fields.

Coaxial stainless steel pump with food-grade rubber impeller mounted directly on the electric motor. All pumps are supplied with a reversing switch for flow inversion.

Available versions:

• 20;
• 30;
• 40;
• 50 (three-phase only);
• 60 (three-phase only).

Technical features common to all versions:

• Mechanical seal;
• Motor shaft in AISI 304 stainless steel;
• Food-grade rubber impeller type “NBSB”;
• 2 hose-tail fittings complete with clamps and gaskets;

Optional:

• Bypass.

The following accessories can be installed on request on this flexible impeller pump:

• Three-phase electrical panel CE-compliant with 24 V NC output for connection to pressure switch or external probes;
• Three-phase electrical panel CE-compliant with flow sensor and stainless steel connection fitting;
• Three-phase electrical panel CE-compliant with timer.
