Hydra-Cell pumps a 'cost-effective alternative'

Michael Smith Engineers has announced that Hydra-Cell pumps are a cost-effective alternative to traditional metering pumps.

Hydra-Cell pumps offer precise and consistent pumping accuracy with flows of +/- one per cent, repeatability to three per cent or better, linearity to three per cent or better and a turndown ratio of 10:1.

The company said Hydra-Cell is a simple pump system from both a mechanical pumping and control standpoint.

It uses a variable speed drive, resulting in virtually pulse-free flow rates controlled by motor speed.

The pumps feature a heavy duty construction to ensure a long service life.

They also include: a fixed-angle cam, which translates rotary motion into linear motion in the hydraulic cells; and diaphragms which are hydraulically balanced ensuring no stress during flexing and roller bearings, immersed in a lubricating oil bath, which provide rigid shaft support.

Hydra-Cell pumps have a sealless design, and can pump liquids at high pressures without leakage, including liquids which contain solids in suspension.

They are also capable of metering viscous slurries and can be run dry.

The standard range of pumps offered covers flow rates from 0.4 lit/min up to 44 lit/min and pressures up to 172 bar.

However, to meet specific requirements and applications, Hydra-Cell offers the facility of modified pump components, along with custom pump head or body castings.

Hydra-Cell pumps can handle a wide spectrum of industrial and commercial fluids, such as propane, butane, ammonia, fuels and additives, through to chlorine, acids and caustics, glues and adhesives, inks, paints, resins and even slurries.
