GISO · long coupled
A frame-mounted pump with a separate motor and coupling. Review the baseplate, alignment and access needed for maintenance.
Flexible-coupling or belt-drive arrangements can be discussed for the project.
End suction pumps
GISO / GIS pumps for water supply, HVAC & industrial transfer.
Built by WY PUMPS
End suction pump assemblies in our workshop.
Match your operating point
2,100 m³/h Maximum series flow
160 m Maximum series head
Series coverage, not a combined operating point. Select the pump and impeller for your required flow and head.
Standard liquid temperature:
−15°C to +120°C. Confirm material, seal and pressure requirements for the actual liquid.
Suitable liquids: non-combustible, low-viscosity liquids free of solids, abrasive materials and fibres.
Send the flow and total head you know. For suction-side review, a liquid level, pipe layout or site sketch is useful even if NPSH has not been calculated.
Choose the installation format
GIS · close coupled
A compact stub-shaft arrangement for direct attachment to a 2- or 4-pole IEC frame motor.
Compare the complete unit dimensions and service access when plant-room space is limited.
Back pull-out service access
The rotating assembly can be removed without disconnecting the pump casing from the pipework. Allow enough service clearance; the required dismantling procedure depends on the coupling and motor arrangement.
Match materials to the liquid
Materials and seals are configuration choices across the series, not a separate coupling format.
- Standard component materials
- Cast iron casing, SS304 impeller and SS420 shaft.
- Project options
- SS316, duplex 2205 and bronze options are reviewed by component and liquid compatibility.
- Seal selection
- Share the liquid composition, concentration, temperature and operating pressure. Review seal materials and any accessory requirements with the quotation.
Why source from WY?
End suction pump assemblies in the production area.
Engineering before manufacture
Compare duty-point options, motor and mounting arrangements. Coordinate pump connections with the upstream and downstream equipment.
Inspection with usable records
Agree the inspection scope and required performance data. WY's service process includes inspection reports with data and photographs for order review.
Support after delivery
Discuss installation guidance, remote troubleshooting and spare-parts requirements. Identify the pump and operating conditions when requesting service.
Start with your flow and head
Send the information already available. The rest can be clarified during selection.
- Required flow and total head, with units
- Liquid, temperature and suction layout or liquid level
- Motor supply, installation space and destination
Review the selected curve, dimensions, material and seal schedule, and supply scope with WY.

Replacing an existing pump?
Send its nameplate, duty point, connection dimensions and photographs of the piping and available space. Confirm the replacement dimensions and motor arrangement before ordering.
What should the quotation include?
Identify the pump, motor, baseplate, coupling and guard as applicable, plus the required documents and inspection scope. Confirm the production schedule, shipping arrangements and support requirements for the order.
