Economical EN 733 (ex DIN 24255) end suction pump, 42 models, cast iron, bronze or 316 stainless. For water supply, HVAC, fire fighting and irrigation.
The classic European standard water pump. Built to EN 733 (formerly DIN 24255), it is economical, robust and easy to maintain, and it replaces most DIN-standard pumps in existing installations.
The back pull-out design lets you remove the pump cover and impeller without disconnecting the suction or discharge piping. Casing, feet and flanges are cast in one piece for rigidity.
Forty-two models use only four shaft sizes and five bearing brackets. Within each size, shafts, bearings, sleeves, seals and impeller fasteners are interchangeable.
Cast iron for standard water, bronze or lead-free bronze impellers for drinking water, and 316 stainless steel for aggressive water.
Yes, EN 733 is the successor of DIN 24255 and uses the same main dimensions.
Yes, 316 stainless steel casing and impeller are available.
Flow rate, head or vacuum level, the liquid or gas and its temperature, required materials, motor voltage and frequency, and any standard or ATEX zone. A data sheet or the nameplate of an existing pump is ideal.
