DIRECT DRIVE ROTARY VANE PUMP

SOVOFLO website SURFLO official website    DIRECT DRIVE ROTARY VANE PUMP

direct drive impeller pump

impeller pumps are known for their reliability and longevity.
The housing material can be selected from brass, stainless steel or engineering polymer, which can be used in the food and beverage industry. Vane pumps are the first choice for most OEM customers.
A built-in relief valve can be provided on request to limit pressure to protect the pump and hydraulic circuit.
A variety of elastomeric materials are available for a variety of fluids, from corrosive solvents to drinking water and food grade liquids.

competitive advantage

Overview

direct-drive rotary-wheel pump is a positive displacement technology in which the flow rate is proportional to the speed. The combination of high-quality raw materials, relatively high flow and pressure performance at the same size, make it the first choice for many water-based applications.

DIRECT DRIVE ROTARY VANE PUMP

VANE PUMPS ARE RENOWNED FOR THEIR RELIABILITY AND LONGEVITY.

Available with brass, stainless steel, or engineered polymers housing for use in the food and beverage industry, they are the preferred choice for most OEMs.
The built-in relief valve, available upon request, limits the pressure to protect the pump and the hydraulic circuit.
Multiple elastomer options are available for a broad range of fluids from aggressive solvents to potable water and food-grade liquids.

COMPETITIVE ADVANTAGES

OVERVIEW

This option takes all the advantage of a direct drive rotary vane pump and eliminates the shaft seal by introducing a magnetic coupling.

ADVANTAGES

Stable, pulsefree delivery

High pressure capability

High flow rate

Reversible

Sealless pump - No dynamic seals, zero leakage

Higher system pressure capability

Well suited to pumping hazardous or hygeinic fluids

No pump or motor shaft wear

No misalignment between pump and motor shafts

Safer fluid containment
