Direct Coupled Centrifugal Pumps


Ease of Maintenance
Pump motor and impellor comes away as one assembly from the base giving full access to all service items without the need to remove the pipework.


ImpellersThe Impellers
There is a vast choice of impellors available.
The diameter can be customised to provide the duty requirement at a high efficiency thus saving on energy consumption.
The range of uniquely designed impellors results in the same pump being able to cover a large working range.


Base PlateBase plate
The base plate on the pumps are pre-drilled to allow the Unit to be secured to the floor / support frame.


High Efficiency MotorsHigh Efficiency Motors
The high quality electric motors are manufactured according to international standards IEC 60034-30 and conform to the requirements of the EC Directive 2009/125 (eco-design for energy-related products).
All motors are standard IP55 weatherproofed c/w drain holes. Higher protection class available upon request.
