Single Stage Pumps

We manufacture a wide range of single stage pumps in a variety of configurations and manufactured to a a number of international standards including API, ANSI and ISO. Pumps range in size from small industrial 25mm end suction designs to large between bearing API 610 compliant machines. No matter what your application you are sure to find a Sulzer single stage pump that meets your requirements.

AHLSTAR A pumps are designed for pumping clean, abrasive or corrosive liquids as well as stocks of various kinds. If the liquid contains gas or air the pump can be modified with either internal or external gas removal construction which stabilizes the operation. The Sulzer Dynamic Seal is specially designed for difficult liquids offering reliable operation and low total sealing costs.

AHLSTAR N pumps are designed for pumping abrasive or corrosive liquids, sludges and slurries containing large particles or long fibers. Special hydraulic design prevents plugging and lets big particles pass. Gas removal systems broaden the scope of applications to include those containing air or gas.

AHLSTAR W pumps are intended for corrosive and abrasive applications where durability is essential. The special hydraulic design reduces erosion while careful selection of parts materials to make them compatible with corrosive conditions, gives extended working life and reliability. Gas removal construction is also offered.

BBS ISO 13709 (API 610 BB2) pumps are primarily used in process applications in refineries and petrochemical plants. The broad pressure and temperature capabilities of this design allow it to be used in the most arduous applications while still providing long and trouble free service. The double entry impeller is particularly suited to low NPSHA applications.
These pumps are also used for main Heat Transfer Fluid (HTF) circulation in solar power plants.

Sulzer HZB pumps are horizontal, single stage, double suction, centerline mounted pumps. They are designed for hot water applications with relatively low NPSH available, primarily as booster pumps for large boiler feed water units in conventional thermal and nuclear power stations as well as for the main Heat Transfer Fluid (HTF) circulation in solar power plants.

The OHH is our latest range of ISO 13709 (API 610 OH2) standard process pumps. Over 70 sizes make up the hydraulic range - the largest on the market. In addition the extensive range of flow and head, care has been taken to ensure that almost any application can be accommodated within the pumps preferred operating range. Designed to meet or exceed the requirements of the forthcoming 9th edition of API 610, the pump also incorporates the extra features commonly specified by the major oil companies.
