OUR BRANDS & SERVICES
Our brand delivers complete technical solutions within the fluid machinery and engineering sectors. Through our range of specialized technologies and product brands, we equip our clients with high-level technical advisory, commercial support, and integrated product solutions — covering pumps, frequency converters, servo drives, PLC-HMI, industrial control cabinets, motors, mechanical seals and assemblies, couplings, gearboxes, and turnkey engineering services (overseas on-site 3D scanning reverse molding of pump replacement parts and equipment debugging by our engineers deployed overseas).
Product Overview
SEEPEX Suction Housing (also called the inlet casing, suction end cover, or pump inlet housing) is the component mounted at the suction end of a SEEPEX progressive cavity pump. It connects the incoming piping to the pump and directs the fluid into the first cavity of the rotor-stator pumping element.
The suction housing is responsible for guiding fluid into the suction-side open cavity of the stator with minimal flow restriction and turbulence. It also provides the mechanical mounting for the rotor shaft bearing, contains the suction-side mechanical seal or lip seal, incorporates an access port for pump priming, and creates the alignment interface between the pump drive end and the stator. In many SEEPEX configurations, the suction housing also supports the suction-side rotor shaft bushing.
SEEPEX suction housings are manufactured in several configurations: standard design with front bearing support for close-coupled motor mounting, foot-mounted suction housing for frame-supported pumps, sanitary suction housing for food/pharma hygienic service, and jacketed suction housing for heat-sensitive or high-viscosity fluids requiring heating at the pump inlet.
Our SEEPEX replacement suction housings are produced from certified castings or CNC-machined from bar stock, with original geometry, flange drilling, bearing bore, and seal chamber dimensions verified to specification.

Why Choose Our SEEPEX Suction Housings
- Bearing Bore Precision — Bearing seat bores are machined to H7 tolerance, ensuring accurate bearing alignment and extended bearing service life
- Seal Chamber Versatility — Housings can be supplied with standard mechanical seal bores, lip seal fits, or gland packing cavities to match the selected seal type
- Original Flange Pattern — Flange drilling and stator-mount interface match the original SEEPEX pattern for direct bolt-on replacement without re-piping
- Material Flexible — Cast iron standard; upgrade to SS 316 or duplex for corrosive inlet conditions without modifying the foot print
- Jacketed Inlet Option — For applications requiring heated pump inlets, jacketed suction housings with integral heating passages maintain fluid temperature before entry into the stator
