POLTAVA FOUNDRY AND MECHANICAL PLANT

In the design of our pumps are used time-tested solutions that combine high strength, durability and reliability with relative ease and "foolproof".

All pumps are executing on the hardened frame made of gray or high-strength cast iron on the liquid lubricant. They have increased oil bathtub, various extents of water cooling of bearing units and are equipped with pressure and suction pipes.

Upon the customer's request pumps could be executed on grease, for the work in special conditions (installation in the holds of dredgers, at an angle, etc.). Additionally, it can be provided by suction pipe (compensator) made of wear-resistant modified cast iron and pipe bend with injection (ejector) made of wear-resistant modified cast iron to facilitate the launch.

There may also be issued lightweight construction pumps assembled on the basis of welded frame (for use on dredgers).

The specialists of our enterprise has been developed a range of MMH (wear-resistant modified cast iron) alloys, that allows you to receive details of high hardness (up to 64-67 HRC) and wear resistance (coefficient of relative wear resistance of 7-7,2). By performance parameters these alloys far exceeding alloys manufactured on the territory of CIS and complies with analogs of world leading companies.

Furthermore, from wear-resistant modified cast-iron are made various details of slurry pipes, pipe bends 90°/135°, 0150600 mm, transitions, suction pipes, pressure pipes, ejectors, and other details, operating for abrasive or percussive and abrasive wear. .
 
1) Pumps are made single-hull, single disc with a single (one piece) detail (hull of the pump/ suction disk/ suction branch pipe). Simple, cheap and repairable design. Recommended for use in relatively light duty. Performed in dimension 5" - 8" on the suction.
 
 
 
2) 1,5 hull, single disc. For permanent installation in the relatively light conditions (TPS (Thermal power station), HPS (Hydroelectric Power Station). They combine high reliability with relative ease and cheapness. Performed in dimension 10"-12M.

3) 1,5 hull, two disc. They are best suited for installation on stationary workplaces (processing plants, gold processing plants, etc.) in severe conditions. Performed in dimension 5M-14".

1. Pumps of I-generation: sand, slurry, sludge, dredge at al. Pumps, flow geometry of recurring pumps produced in the USSR and the CIS, but manufactured using modern technologies from quality materials with modern design solutions. Their operating time is 2-10 times greater than the analogues of other domestic producers. However, since the geometry of the flow part did not change significantly, the efficiency coefficient remains at the level of domestic analogues (55-70%).

2. Pumps of II-generation: high-pressure, high reliability, sand, sludge, special at al. They are used usually at processing plants for hydrotransportating of crushed products. They are made on the basis of our modern run-time constructive solutions, but the geometry of the flow part corresponding analogues of world's leading manufacturers.

These pumps have a high efficiency coefficient (up to 82%), but they compare favorably to analogues produced by western companies by reinforced construction, increased reliability, loyalty to the "domestic" approach of equipment maintenance, "indestructibility" and "foolproof". Furthermore, they do not have sophisticated components that requiring a qualified staff and specialized equipment for service.

3. Pumps of II-generation: slurry, gravel, sludge et al.Are usually used, in quarries, opencast mining, on dredgers and other areas for transporting of uncrushed products, as well as the tail pumps where required pumping of large fractions and (or) larger volumes.

Pumps of the HG, GR group and others are made on the basis of our modern run-time constructive solutions, but the geometry of the flow part corresponding analogues of world's leading manufacturers.

These pumps have a high efficiency coefficient (up to 85%), and as the pumps of the previous group compare favorably to analogues produced by western companies by reinforced construction, increased reliability, loyalty to the "domestic" approach of equipment maintenance, "indestructibility" and "foolproof ". They can be manufactured in a lightweight version.
