The Water Hydraulics Company Ltd. products

The power centre combines the operation of an axial piston high pressure   desalination pump with an axial piston motor utilising the pressure  in the waste brine to assist the electric motor in driving the pump and so   reducing the power requirement to typically less than 3 kW/m³ of permeate.  The power centre has been purpose designed and built for the RO market. The power centre is driven via a splined shaft from an electric motor. This turns the pump rotating group which also drives the energy recovery rotating group  via a simple splined mechanical coupling.

The power centre combines the operation of an axial piston high pressure desalination pump with an axial piston motor utilising the pressure in the waste brine to assist the electric motor in driving the pump hence reducing the power requirement to typically less than 3 kW/m³ throughout. The power centre has been purpose designed and built for the RO market.

The Janus Axial Piston Pumps are totally oil free, clean and completely safe to use in all locations including Atex environments. Advanced material technology ensures high velocity and heavily loaded surfaces can operate effectively with water as their only  coolant/lubricant;.

A patented design of control valves. Available in DN3 and DN6 0-30 l/min.

A patented design of control valves. Between 0-100 l/min the direct acting valve can control system pressure electronically up to 160 Bar.

An integrated controller configured to offer open loop, closed loop or human interface control of the electronic pressure and flow control valves.

A patented design of control valves. Available in DN6 & DN9 direct acting for flow rates up to 50 l/min. Also available DN16 in pilot actuation versions. Max pressure rating 160 Bar.

A patented design of control valves. Available in DN6 & DN9 direct acting for flow rates up to 50 l/min. Also available DN16 in pilot actuation versions. Max pressure rating 160 Bar. Actuation via solenoid, manual, pilot, air or fluid is also available. A patented range of valves which control the directional flow of corrosive fluids in hydraulic systems. Designed For operation on tap water to EU directive 98/83/EC. The valves offer high efficiency with minimal energy input for actuation. Also available in 4/2 & 3/2 control functions; please see data sheet for further information. Various porting configurations including stand alone (BSPP), TWHC manifold or Cetop 3 are available. Please see manifolds data sheet for options and cavity details.

Totally oil free, clean and completely safe for people, processes and products. As a result of employing advanced materials, high velocity and loaded sliding surfaces can operate effectively with water as their only coolant/lubricant.  The potential for cross contamination of the system fluid or the lubricating oil is removed.
