AHI series vertical semi-submersible motor pumps

DESIGN FEATURES AND SCOPE OF APPLICATION:

• principal application is to pump acids, alkali and contaminated liquids from tanks and pits;
• volume content of solids (up to 2 mm) in the pumped medium up to 1.5%;
• working temperature from ­- 40° to + 90°С;
• immersion depth from 0.8 to 1.3 m (not including optional installation of a suction nozzle with a check valve);
• require no maintenance or control, including additional protection controllers;
• bearings removed from the area of contact with the pumped media and equipped with additional protection from exposure to their vapors;
• base plate shielded with stainless steel to prevent corrosion caused by exposure to the pumped medium;
• comply with TDFA.062621.050.TU;
• comply with the Customs Union Technical Regulations TR TS 004, 010;
• certificates for design and manufacturing nuclear power plant equipment.

 

LIQUID END MATERIALS:

 

• 06XH28MДT alloy (C 0.06%, Cr, Ni 28%, Mo, Cu, Ti);
• 12X18H10T steel (C 0.12%, Cr 18%, Ni 10%, Ti up to 1.5%);
• 10X17H13M2T steel (C 0.10%, Cr 17%, Ni 13%, Mo 2%, Ti up to 1.5%);
• 09Г2С steel (C 0.9%, Mn up to 2%, Si);
• 35ХМЛ steel (C 0.35% max, Cr, Mo).

 

 

 

 

 

A suction nozzle (of a specified length) with a filter can be fitted on customer’s demand. Available with a check valve, which is highly advisable when the residual level of the pumped medium is below the impeller.

Modern equipment is used to balance the rotor.

A solid shaft gives rigidity to the cantilever structure, which, together with strengthened bearings, guarantees a long service life of the pumps.
