Pump Family Designed for Water MarketDallas, Texas, USA – March 22, 2007 – Flowserve Corporation is expanding its family of MEN water pumps to the North American market. This North American expansion allows Flowserve to offer comprehensive worldwide availability of all MEN sizes in both frame mounted and close coupled configurations.The MEN single-stage, end-suction pumps deliver maximum mechanical and hydraulic flexibility, and are ruggedly designed to provide reliable performance in a variety of water services.
These areas include water supply, water treatment, irrigation, drainage, filter cleaning, water circulation and HVAC.The Flowserve MEN is constructed with a one-piece bearing frame that is available in three sizes to ensure parts interchangeability among pump sizes and configurations. The resulting reduction in inventory costs, along with the MEN’s hydraulic flexibility and minimal maintenance needs, provides users with significant cost savings.
Features of the pump family include:
• A volute casing design with raised face flanges• A precision cast closed impeller with machined shrouds that is dynamically balanced for high efficiency• Greased-for-life reinforced ball bearings • An open seal chamber with flow modifier• An oversized stainless steel shaft that minimizes deflection and reduces wear• A back pull-out design that facilitates inspection and maintenance• An elastomeric bellows mechanical seal that provides bidirectional operation and accommodates misalignment, end-float and seal face wearOperating parameters for MEN pumps include: flows to 800 m3/h (3500 gpm), heads to 140 m (450 ft), pressures to 16 bar (230 psi) and temperatures from -10ºC (15ºF) to 140ºC (280ºF).The close-coupled configuration of the MEN water pump is the MENBLOC.
Not requiring a baseplate or coupling, the MENBLOC is an economical alternative to the frame-mounted MEN. Its reduced footprint permits its use in restricted spaces. The MENBLOC accommodates flows to 340 m3/h (1500 gpm), heads to 16 bar (230 psi) and temperatures to 100ºC (230ºF). The MEN and MENBLOC pumps are CE marked and comply with the dimensional requirements of the latest editions of EN 733 and DIN 24 255.
Casing flange connections meet ANSI B16.1 Class 125 and 250 dimensional standards. Vent, gauge and drain connections are NPT. Other MEN configurations include: MEN-SP cantilever sump pump and MEN-TI diesel-driven fire pump.
