Seal-less pumps ideal for recycling and
cleaning
Many factors in the use of water-based chemicals and solvent cleaning systems have made the choice of the fluid pumping system used even more critical, particularly for recycled fluids
Cleaning is an essential requirement in many industries: as water becomes less available and solvents typically used in cleaning applications become more expensive, recycling of the cleaning fluids becomes a cost / energy-efficient alternative To conserve energy, the use of more aggressive and effective cleaning fluids is increasing, which results in reduced volumes being pumped

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.
Small pump package delivers big performance
The Micropump innovative I-Drive electromagnetic drive has been developed to meet the increasing demands from OEM engineers and machine builders who require high performance from less space
Furthermore, in order to reduce the volume of fluids required, today's cleaning systems typically operate at higher pressures with lower flows to ensure that effective cleaning is maintained.
All these factors make the choice of the right pumping technology ever more critical.
Hydra-Cell sealless pumps, available through liquids handling specialists Michael Smith Engineers, are particularly effective for cleaning applications and are ideally suited to handling recycled fluids or fluids containing particulates.

Where reliability and durability are high on the list, when choosing a pump for transferring corrosive or thin liquids at higher pressures, Viking LVP stainless steel vane pumps, are an ideal choice
Plastic, leak-free pumps for hazardous liquids
A new range of plastic magnet-drive centrifugal pumps, designed for use in the most corrosive and challenging environments, have recently been introduced by pump specialists Michael Smith Engineers
These high pressure positive displacement pumps incorporate hydraulically balanced diaphragms and have no rotating seals.
Pump types which incorporate seals are far less effective on these duties as their seals can be destroyed by particulates as small as 25 microns.
Hydra-Cell pumps are 'simply built to last' operating with minimal stress thanks to important design features.
The pump drive shaft is rigidly held in the pump housing by a large tapered roller bearing which is immersed in a lubricating oil bath, and a fixed angle cam translates rotary motion into linear motion to the hydraulic cells, which displace the diaphragms via pressurised oil.
This results in hydraulically balanced diaphragms, so stress is eliminated.
This greatly extends the period between planned servicing and can offer the operator savings in maintenance costs and reduces the frequency and likelihood of any unplanned, costly downtime.
The pumps cover a wide range of flow rates from 0.4 lit/min up to 128 lit/min and pressures up to 172 bar, providing repeatable and accurate output.
Hydra-Cell pumps can handle dirty liquids and liquids with particulates, they are seal-less by design, leak-free and as they are self priming they can be run dry, making them ideal for cleaning applications.
Hydra-Cell pumps are also very energy efficient and so offer operators considerable savings in running costs when compared to traditional multi-stage rotary pumps.
As well as cleaning duties, Hydra-Cell pumps can handle a wide spectrum of industrial and commercial fluids across numerous applications including; food processing CIP, machine tool cooling, reverse osmosis and separation, spray drying and abrasives, paper mill applications and oil production and refining.
