GH series hermetic metal motor pumps (horizontal design)

DESIGN FEATURES AND SCOPE OF APPLICATION:

• leakage elimination, working chamber separated from environment by a stationary shield made of stainless steels, alloys and technical ceramics;
• recommended to replace pumps with shaft mechanical seals with complex piping, to be used with combustible, explosive and toxic media;
• torque transfer via SmCo and NdFeB permanent magnets;
• minimum maintenance required during the entire service life, does not require barrier fluid;
• liquid end made of stainless steels and alloys;
• volume content of non-abrasive solids (up to 0.2 mm) in the pumped medium up to 0.5%;
• used to handle aggressive and toxic liquids, and oil products;
• working temperature from –40° to +250°С;
• excellent anti-cavitaion properties, optional designs include pre-started axial stage (inducer);
• comply with TDFA.062443.300TU;
• comply with the Customs Union Technical Regulations TR TS 004, 010, 012;
• certificates for design and manufacturing nuclear power plant equipment.
