GEA Hilge Centrifugal MAXA Pump

HILGE, Maxa PumpHeavy-Duty Pumps for Industrial Processes – The GEA Hilge MAXA range in the GEA Varipump line offers single-stage end-suction centrifugal pumps designed for heavy-duty operation in industrial processes. The major dimensions and characteristics of these pumps correspond to DIN EN 733 and DIN EN 22858.

High Quality Throughout

The GEA Hilge MAXA range is made from deep-drawn, rolled stainless steel in AISI 316L (1.4404). Flexible mounting options are available, such as a close-coupled pump, a close-coupled pump with bearing bracket or a base plate pump version (with motors up to 160 kW). The GEA Hilge MAXA range employs closed impellers with optimized efficiency and NPSH. Flange or thread connections according to ANSI or DIN standards are available.

For some GEA Hilge MAXA pump sizes, an inducer for NPSH improvements is available as an option, also a channel impeller for pumping media with high solids content.

Shaft Seals – Choose the One to Suit You

A wide range of shaft seal options is available to suit different media and applications. The mechanical seals used in the GEA Hilge MAXA range conform to DIN 24960. The single inboard seals maintain the optimum position in the liquid. This ensures efficient cleaning, lubrication and cooling.
