POLTAVA FOUNDRY AND MECHANICAL PLANT

Soil pumps, gravel pumps, slurry pumps, refuller pumps and other HG,GR, LG series. They are usually used in quarries, open pits, dredgers and other places for transporting non-crushed products, as well as tail pumps, that is, where pumping of large fractions and (or) large volumes is required. Pumps of the HG, GR, etc. groups are manufactured on the basis of our modern, time-tested design solutions, but at the same time, the geometry of the flow path corresponds to analogues of the world's leading manufacturers. These pumps have a high efficiency (up to 85%), but compare favorably with analogues from Western companies in their reinforced design, increased reliability, loyalty to the “domestic” approach to equipment maintenance, “indestructibility” and “foolproofness”. They also lack complex components that require both qualified personnel and special equipment for their maintenance.

Explanation of pump names

shl9pa                                                                                                

1. Suction nozzle diameter in inches (from 2" to 28")(36");
2. Discharge pipe diameter in inches (from 1.5" to 24")(32");
3. Pump series (1 - 2 letters). Several series of pumps are produced, different in terms of the geometry of the flow path, depending on the work that the pump has to perform:


- W, WK – high-pressure universal pumps;
- MV – medium head pumps with maximum efficiency, for operation at the OF;
- HG – pumps for large volumes of pumping;
- GR – the same, with the possibility of pumping maximum fractions;
- LG – high-speed, for large volumes of liquid pulp pumping, most suitable for tailing facilities of mining and processing plants;
- CW, DW – clear water / dirty water - pumps for clean or waste water with a simplified design of working bodies;


4. Working body assembly scheme - A, B, C, D:

Scheme A - Single case, single disc
With a single (solid) part (housing / suction disk / suction pipe). Simple, cheap and maintainable design. Suitable for small pumps (2"-4") as well as 5"-9" pumps operating in relatively light conditions.

Scheme B - One and a half body
Best of all are suitable for installation on stationary workplaces (OF, ZIF, TsOF) in severe conditions. They combine excellent wear resistance with a moderate price for spare parts. Available in sizes 5"-14".

Scheme C - Single case, double disc
They are used to work in difficult and especially difficult conditions, with various fractions and unstable conditions. Available in 10"-20" sizes.

Scheme D - Double-case, double-disk
Used in pumps 20", 28", 30".


5. Size and construction of the rack - numbers and letters. Letters may be missing if the design of the rack is standard - cast on liquid lubricant:

- digits from 0 to 11 – rack standard size;

- letters:

- L – light version on a welded frame;

- S - solid grease;

- V – vertical execution;

* Maximum allowable revolutions and loads for each specific rack.

 

6. Diameter of the working wheel in mm and direction of rotation:

- diameter from 240 to 1890 mm;
- R or L - direction of rotation.

 

7. The width of the flow in the working wheel in mm (from 25 to 350 mm).

 

8. Conventional designation of the manufacturer.

 

EXAMPLE: 12/10НG-С-(6SL)-710R-180-PET  – gravel pump, with 12/10 in. suction/pressure nozzles, double-disc single-casing, light version, No. 6 strut, solid lubricated, with Ø impeller 710 mm, clockwise rotation, with a working chamber width of 180 mm, manufactured by PFMP
