ViscoTwin Pumps Overview

ViscoTwin pumps are setting a new standard for sanitary design. The mechanical seals are fully exposed to 100% of the passing CIP liquid and the pump is 100% drainable by design. There are almost no limitations in media viscosity, pumping product from water to silicone at discharge pressures from 230 to 360 psi. With dual mechanical seals, the pumps can run dry for extended periods. It primes low viscous media up to 3 feet and operates with extremely high suction at an NPSH of 3 to 4 feet. It does not get airborne ever. The pump is fully by-directional.

Because product is moved axially to the shaft, it can operate at low speed for high viscous product and very high speed for low viscous media, making it a perfect CIP return pump that never gets airborne.

The pump is bi-directional by design.

The pump has a higher tolerance for debris and abrasive media than most other pump designs.

The pump does not “pinch” soft items at the inlet or discharge, simply moves it though the screw channels without size restriction.

Largest viscosity range from 0 to 1 mio cps

It generates almost no pulsation and makes therefore an excellent dosing pump.

Very low wear and tear lowers costs for maintenance compared to other pumps for high viscous media.

Safe to run dry for extended periods of time when using water flushed seals due to non-touching metal-to-metal rotor design.

Pumps sensitive media gently because of the axial flow design.

Pumps media with gas content up to 60% without issues.

Product lift capability up to 4 feet.

Excellent speed control characteristics compared to Rotary Lobe Pumps.

Large temperature span with standard configuration up to 266F.

Pump heads can be installed in serial arrangement without bypass valves.

Particulate sizes up to 1-1/2” Inches.

Can be installed sideways and upside down with small bearing frame adjustments.

Heat jacketed pump heads provide a larger heating surface compared to other pump systems
