When a smooth flow is the priority, when you need to handle thin or thick liquids, the choice of pump is critical, according to the Pump Company.

Understanding the rheology of the fluid and obtaining the correct balance between pump and system has allowed the company to successfully specify and supply the Varisco V series of internal gear pumps on a variety of applications.

The pump is able to handle water-thin liquids or high-viscosity liquids such as: bitumen, molasses, resins and polymers.

Giving a constant capacity that is directly proportional to the rotation speed and virtually independent of the pressure, the pump is able to give a smooth flow without pulsations or pressure peaks that cause vibration or destroy the pumped liquid.

The pump has only two moving parts – the rotor and idler gear – and only one shaft.

It is totally reversible and gives full performance in either direction.

The high vacuum created by the pump permits rapid self priming at the maximum height, made possible by the physical characteristics of the pumped liquid.

A key feature of the Varisco V series gear pump is the slow speed of rotation coupled with the low rate of wear.

The number of teeth on the rotor and idler are not multiples of the other.

This means that wear is evenly distributed over the gears since each tooth on one gear touches on the other gear the same number of times.

Peak performance can be obtained due to the rotor-wear adjustment system, which maintains the high volumetric efficiency of the pump.

The heavy-duty casings are manufactured in ductile iron, steel or stainless steel.

The pump can be fitted with a variety of sealing options, including a magnetic coupling.

Heating jackets, single or double relief valves and a variety of bearing bushes are available.

The pump can be certified in accordance with the Atex standard, is suitable for use in the petrochemical industry and can be supplied in accordance with API 676.
