Capability
Foundry to final test, under one roof
Casting, machining, assembly and performance testing happen in the same works, which is why drawings and material changes can be handled without a supply chain in between.
-
Casting
In-house foundry producing high-chrome and wear-resistant iron castings for wet-end components.
-
Machining
CAD and CAPP are used for design and process planning; impellers and liners are machined to drawing.
-
Assembly & testing
A dedicated slurry pump test station verifies performance before dispatch, backed by a physical and chemical laboratory and metrology room.

Service
Selection, commissioning and wear-part supply
Pumps are sold against a duty point, not from a shelf. Our engineers size the pump, support commissioning and keep wear parts available for the life of the unit.
Before the order
Selection sheets, performance curves and material advice for abrasive or corrosive duties — including special designs for non-standard installations.
During installation
Installation and commissioning guidance, operator training, and test records handed over in a documented file.
After handover
Wear parts, impellers and liners held to the original drawing, with scheduled inspections and follow-up.
Enquiry
Send us the duty point and we will size the pump.
Flow, head, medium, solids content and site conditions are enough for a first recommendation. Our engineers reply in English, usually within one working day.
