Fixed Speed Pressure Sets

our fixed speed pressure sets will operate between two pressures, start and stop which can be adjusted at the pressure switch to suit demand. There will be a 50% volume storage in the pressure vessel approx 12ltrs before the pump will restart. 

Constant / Variable Speed Pressure Set

The Teknospeed Pump will give you constant pressure and variable volume. As the demand increases the pump will speed up to the keep the volume constant. 
Avantages of using this type of pump control is you will get a longer life out of the pump due to the variable speed and slow rotations. The pump will start/stop slowly extending the pump life and reducing the mechanical stress on the pump. Reduce energy use resulting in Energy Saving.
1.1kW, 230 V, 6.8amps.

Drainage Pumps

Pumps ranging from domestic pumps suitable for clear and sump water, drainage of flooded rooms, garden fountains, irrigation and movement of rain water up to industrial pumps for the removal of nusciance water from sumps, excavations etc.


De-ionisation by automatic Twin-Column Ion-Exchange will completely remove the majority of dissolved minerals from raw water. Regeneration of the ion-exchange resins is effected with acid and caustic which must be accurately dispensed for safety and efficiency.

Water Treatment

Groundwater from wells and boreholes is subject to impurities picked up from rock strata, such as iron and calcium. Mains water is additionally subject to chemical contaminants from pesticides and industrial pollution and to other impurities from the recycling process. The most common problem is scale, the solution being a simple ion-exchange softener. However, to solve your own water supply problems, you often need the accurate analysis and professional chemical and engineering skills that we can provide.
