Centrifugal pumps HCM

Horizontal centrifugal monoblock pumps brand HCM.

* Pumps brand HCM are centrifugal, bessolnechnymi, the magnetic coupling, which eliminates leakage of the pumped liquids.
* Details of the flow of the pump is made of polypropylene, PTFE and ceramic, which provides a high resistance to aggressive environments.
* It is possible to manufacture parts of the flow of steel 12X18H10T.

Pump type HCM with a flowing part of the polypropylene
Purpose: for pumping acidic and alkaline solutions, electrolytes, deionized water and other aggressive and neutral liquids.

Pump type HCM with a flowing part of steel 12X18H10T
Purpose: for pumping acidic and alkaline solutions, electrolytes, deionized water and other aggressive and neutral liquids, and flammable liquids and GZH.

Pump type HCM, equipped with explosion-proof motor
Purpose: for pumping acidic and alkaline solutions, electrolytes, deionized water and other aggressive and neutral liquids, and flammable liquids.

Horizontal centrifugal monoblock pumps brand HCM designed for pumping of various neutral and chemically active liquids with specific volumetric electric resistance less than 105 Ohm×m that do not have a destructive effect on the material flow of the pump (polypropylene and ceramics):

* tap water, distilled, deionized;
* aqueous solutions technically detergent (pH of not more than 12);
* solutions-based fluorocarbons;
* the alkali concentration of not more than 30%;
* acid solutions with concentrations of:

o nitrogen is not more than 40%;

o sulfuric not more than 70%;

o phosphorus - not more than 90%;

o salt - no more than 35%.

Requirements for pumped liquid:

* Temperature: 5°C to 80°C;
* Concentration of suspended particles should not exceed 1.25 mg/cm3;
* Particle size: up to 0.25 mm;
* Liquid density (ρ): not more than 1500 kg/m3;
* Kinematic viscosity: not more than 10×10-6 m2/S.

In order to avoid failure of chemically resistant pump must on the suction pipe to provide a filter for cleaning mechanical impurities with cells 0,2...0,25 mm square filter surface for HCM 1/10 = 0,024 m2, for HSM 3/25M = 0,06 m2, for HCM 6/30M = 0,12 m2, for HCM 9/25M = 0,18 m2, for HCM 12/25M = 0,24 m2, HCM 20/25M = 0,42 m2, providing three times the nominal flow, and when the presence in the fluid of the ferromagnetic particles is necessary to the suction pipe to use magnetic filter.

No operation of the pump, pumped empty the fluid. Protection of the electric pump unit from running dry provides device USND to 0.5, which provides automatic the engine is off when dry-running (without fluid), preserving the life of pumping equipment.

Design features and advantages of hermetic centrifugal pumps

By construction, the pump is a centrifugal monoblock, Bassalygo, sealed - has a magnetic clutch that completely eliminates leakage of the pumped fluid. On the motor shaft installed external magnetic coupling, consisting of a body and 8-10 two-pole permanent magnets. Flowing a portion of the centrifugal sealed pump consists of snails with separating flange, the impeller and with the built-in internal coupling. It reinforced two metal discs, preventing deformation of the flange and the rear the wall of the cochlea of the operating pressure. The impeller on the two sleeves, consisting of material F4C20, and with two screw grooves, installed ceramic axis between two ceramic plates.

The materials from which made running part of the chemical pump, provide high resistance to aggressive environments.
