Product Development

The new version of the ZEM pump exemplifies the innovative development of the product. The ZEM pump is a new generation of products designed and manufactured by SULZER based on years of practical experience and professional technology. It fully meets the requirements of practical use. Optimized design and material technology enable the ZE8 to meet all the requirements of heavy-duty pumps. It meets or exceeds the very stringent requirements of API610 8th edition. In addition, the Z-series standard structural system provides extensive interchangeability between components of different series pumps (such as shafts, sleeves, bushings, bearings, and seals, etc.).

Conclusion: High efficiency, stability, and low operating costs.

Scope of Application

This series of pumps is designed for the transportation of most media in refinery processes. The scope of application ranges from low-temperature liquefied gas and light and heavy fuels to high-temperature gasoline containing solid particles and oil residue.

• Refineries
• Petrochemical plants
• Gas processing
• Coal processing
• Offshore platforms

The ZE8 pump can also be used as a turbine for energy recovery.

Operating Parameters

Design

The ZEM pump is a horizontal, single-stage, single-suction, closed impeller, radially split, center-supported heavy-duty process pump.

The suction flange is horizontally mounted, and the discharge flange is vertically upward. The flanges can withstand large pipe loads. The flanges comply with ANSI standards, and the suction and discharge flanges have the same pressure rating.

There is a very tight gasket seal between the pump body and the pump cover, and between the pump cover and the seal cover.

The dimensions of the sealing chamber fully comply with API682, and it is suitable for installing single-end face mechanical seals, double-end face mechanical seals, and tandem mechanical seals. Installing a cartridge mechanical seal is the standard form. The connections of the flushing, cooling, heating, quenching, and buffer liquid pipelines comply with API standards.

The ZEM pump is equipped with a robust welded combination API base with a sump and lifting lugs.
