Why Hydra-Cell?
Hydra-Cell pumps are seal-less. No seals, no seal wear – No leaks. No loss of performance. No frequent repairs. Less downtime. Long-term reliability, with minimal routine maintenance and low repair costs. Absence of dynamic seals (cf. for example, gear pumps) means that the Hydra-Cell avoids problems with non-lubricating fluids, or liquids that crystallise on exposure to air.

Hydra-Cell’s unique multi diaphragm single pump head and compact design mean significant footprint savings and acquisition cost savings.

Hydra-Cell pumps can handle solids up to 1mm, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

The flow rate of a Hydra-Cell pump is constant, regardless of pressure. (See graph.) The relationship between flow and pump speed is a straight line. Flow is easily controlled within ± 1% accuracy simply by controlling pump speed – with turndown ratios of 10:1 or better.

Flow is steady, with little pulsation.

Hydra-Cell pumps can run dry without damage. Innovative Kel-Cell technology protects diaphragms even in abnormal system conditions.

Energy savings. Compact and highly efficient (80-85%), a Hydra-Cell pump can be fitted with a smaller motor than would be required by many much bigger pumps for equivalent flows and pressures.

The low-shear pumping action of a Hydra-Cell pump (cf. centrifugal pumps) reduces heat input into the system – a clear advantage on a long feed line if the product is temperature sensitive.

Though not qualified for Hygienic duties, Hydra-Cell pumps are widely used in the food industry because of their seal-less design and ability to handle particulates, abrasives, corrosives, caustics and hot liquids. Common applications include spray drying systems, coating, transfer of process liquids, mixing and dosing. Liquid end can be supplied with internal parts polished to a mirror finish surface, 0.4 Ra.

The pumps are ideal for pumping hot or cold, cleaning and sterilising agents in C.I.P S.I.P. systems, high pressure road-tanker, tank-wash systems and hand-held wash-down guns.

Why Hydra-Cell?
Hydra-Cell pumps are seal-less. No seals, no seal wear – No leaks. No loss of performance. No frequent repairs. Less downtime. Long-term reliability, with minimal routine maintenance and low repair costs.

Hydra-Cell has a low shearing pumping action compared with traditional pumps used and therefore affects shear-sensitive fluids much less.

Hydra-Cell pumps can handle solids up to 500 microns, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

Most pumps in the Hydra-Cell range can operate at any pressure from <1 bar up to at least 70 bar. Some models up to 170 bar

The flow rate of a Hydra-Cell pump is constant, regardless of system pressure. The relationship between flow and pump speed is a straight line. Flow is easily controlled within ±1% accuracy simply by controlling pump speed – with turndown ratios of 10:1 or better.

Flow is steady, with little pulsation.

The droplet size produced by a given spray nozzle depends on pressure, which is related to flow. Hydra-Cell pump flow is accurately controlled by controlling pump speed.

Categories: Industrial Pump Applications


Simple build and a design with no dynamic seals give Hydra-Cell pumps big advantages in many mining and quarrying applications.

For example, grey water with abrasive solids often gives trouble to piston plunger pumps and multi-stage centrifugal pumps, whose designs rely on seals exposed to wear. Seal-less Hydra-Cell pumps handle recycled water easily. Also corrosives and caustic liquids.

High pressure capability and low pulsation – basic Hydra-Cell features – make the pumps ideal for seal-flushing, protecting high-volume slurry and ground water pumps from expensive early failure.

Physically compact and energy efficient, using relatively small motors, Hydra-Cell pumps fit readily into mobile machinery.

Meeting the performance criteria of API675, the Hydra-Cell pump offers linear, repeatable, accurate steady flow.

The compact Hydra-Cell gives the advantages of large traditional hydraulic diaphragm pumps, but at a fraction of the initial cost, spare parts costs and energy costs.

For example, at a given flow and pressure, a traditional pump with a 15kW motor can be replaced with a Hydra-Cell pump with 5kW.

Flow rate is varied by speed control offering turndown ratios of 10 to 1 or better

Why Hydra-Cell?
Hydra-Cell’s unique multiple diaphragm head design means that:

1. Pulsation dampers may not be required. See graph comparing pulsation of a typical hydraulic diaphragm metering pump with that of the Hydra-Cell pump.

2. For equivalent flow/pressure performance, the physical size of a Hydra-Cell pump is very much smaller than that of the more massively constructed typical traditional metering pump. (See comparison.) The Hydra-Cell’s compact design not only gives it a smaller footprint, but also reduces life-cycle costs.

Flow rate is near constant regardless of variations in system pressure.

Hydra-Cell’s unique check valve design allows it to handle particles, including slurries and any crystals which may form in the liquid.

Meets and exceeds the perfomance characteristics of API 675.

Reverse Osmosis

Written on February 21st, 2010 by
Categories: Industrial Pump Applications


The seal-less nature of the Hydra-Cell pump (which is also ATEX approved) enables charged and dirty liquids to be processed without need for fine filtration to protect the pump.

The pump needs little maintenance and can operate on continuous duty at high pressure.

Pulsation is low, so dampeners may not be required.

Seal-less design marks out the Hydra-Cell from other RO pumps and is the basis of its long service life – many of the liquids pumped are harmful to pump seals. The pump is tolerant of small solids, resistant to chemical and corrosive attack.

Energy costs, a serious problem with many pumps on continuous duty, are held down by the high efficiency and low horsepower requirement of the Hydra-Cell pump.

Why Hydra-Cell?
Hydra-Cell pumps are seal-less. No seals, no seal wear – No leaks. No loss of performance. No frequent repairs. Less downtime. Long-term reliability, with minimal routine maintenance and low repair costs.

Hydra-Cell pumps can handle solids up to 500 microns, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

Flow is steady, with little pulsation.

Energy savings. See comparision table for examples of Hydra-Cell v centrifugal pumps.

The pump is tolerant of operator error as it can run dry and the patented Kel-Cell mechanism protects the pump from adverse inlet conditions, such as a blocked filter or an accidently closed valve.

Pulp and Paper Industry

Written on February 21st, 2010 by
Categories: Industrial Pump Applications


In duties ranging from paper coating and preparation to high pressure cleaning, wet-end trimming and extremely accurate metering (exceeding API 675 standards for metering pumps) the reliability of Hydra-Cell seal-less pumps is well-proven in the paper industries.

The pumps are handling recycled water, abrasive fluids, fluids with solids in suspension, chemicals, non-lubricants and many other difficult liquids. Many of the fluids used are abrasive and react with air to crystallise or harden, which can cause problems with pumps that have mechanical seals. Hydra-Cell’s seal-less pump design means that this is not a problem.

High pumping efficiency (85% compared for example with 45% for a typical centrifugal pump) is enabling mills to save energy, while also reducing maintenance and repair costs.

Electronic control of flow (via motor speed) makes automation simple and inexpensive. Very low pulsation, avoiding need for pulsation dampeners, reduces cost of many metering and chemical injection systems, and cuts wastage at web trimming stage.

Why Hydra-Cell?
Many of the chemicals used in the paper and pulp industry are abrasive or react by crystallising or hardening when they come into contact with air. This can lead to problems with mechanical seals creating extra maintenance work. Hydra-Cell’s seal-less design gives large savings in maintenance.

Energy savings. Compact and highly efficient (85%), a Hydra-Cell pump can be fitted with a smaller motor than would be required by many pumps for the same flows and pressures. See table comparing examples of Hydra-Cell v centrifugal pumps.

Hydra-Cell pumps can handle solids up to 1mm, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.

Most pumps in the Hydra-Cell range can operate at any pressure from
<1 bar up to at least 70 bar. Some models up to 170 bar.

Vehicle Washing

Written on February 21st, 2010 by
Categories: Industrial Pump Applications


The high costs of using and disposing of water oblige vehicle wash systems to rely increasingly on recycled water. Even after filtration this will contain chemicals in solution and is likely to carry particles of grit and other contaminants. Pumping it is potentially damaging for pumps with seals.

Operating at pressures above 40 bar, even using clean water, may cause packings and seals of piston pumps to be changed every 6 months. Hydra-Cell’s seal-less design means that this maintenance is not needed.

Sealed pumps may be vulnerable in a low pressure system. In cleaning systems working at higher pressures (e.g. above about 20 bar) the risks of rapid seal wear, loss of performance and premature pump failure increase.

Hydra-Cell seal-less pumps are used in vehicle cleaning systems not only for their high pressure capability, but because of their simple build, low maintenance and reliability. They tolerate chemicals and abrasive particles (up to1mm or more) without needing fine filtration. They are also energy efficient – a big factor in their exceptionally low operating costs.

Why Hydra-Cell?
Hydra-Cell pumps are seal-less. No seals, no seal wear – No leaks. No loss of performance. No frequent repairs. Less downtime. Long-term reliability, with minimal routine maintenance and low repair costs.

Hydra-Cell pumps can handle solids up to 1mm, or more. They can be pumped without fine filtration. System costs are reduced and maintenance is simplified.
