Usage areas: power plants, agricultural Irrigation and drainage, oil industry, building system, water, treatment and pressurization, mining,
chemial industry, heating, ventilating and air conditioning, marine, fire fighting, food and beverage industry, iron and steel industry.

 DESIGN ENGINEERING:


• GM series pumps have designed for pumping non-abrasive and small particulars liquids.
• GM series pump has just one impeller, pump and motor is connecting by coupling. It gives your advantages for easy disassembling.
• Pump Dimensions are according to EN 733 - DIN 24255 standard.
• Suction and discharge flanges according to EN 1092-2 / PN 16.
• GM series have a closed impeller, impeller blades located between the balancing holes to minimize the axial load is taken in dynamic
load balancing. Sealing is provided by mechanical seal.
• Easy disassembly to pump and change impeller, bearings, and seals.
• All impellers are statically and dynamically balanced according to ISO 1940 class 6.3.
• The main dimensions of complementary models may different from other manufacturers.
• Direction of rotation is clockwise viewed from the driver end.
• Optionally, pumps can be manufactured with shaft bushings and/or wear rings.
