Type D Horizontal Multi-stage Centrifugal Pump

612-1

It's segmental multi-stage centrifugal pump, mainly supporting by foot, and connecting suction, middle and discharge part by tighten bolt. Here are they advantages:

1. Wet part such as impeller, guide vane, using CFD flow field analysis to optimise the design, which is high efficiency;

2. The static sealing between pump suction segment, middle segment and discharge segment are metal-surface sealing and O- ring double sealing, and pump shaft seals are sealed by ramie packing or mechanical sealing, which are safe and reliable;

3. Wide spectral spectrum, large capacity pump technology take lead in China;

4. The rotor using static balancing and dynamic balancing process to restrict rotor runout, and the pump runs steadily with low vibration;

5. The shaft in carbon steel、alloy steel and stainless steel will going through multichannel heat treatment process, which makes it high rigidity and good stability;

6. With special shoulder posotioning structure, it's more reliable for impeller positioning and safer for operation;

7. High quality castings or forgings are used in the suction and discharge segment of pumps to ensure hydraulic efficiency and reliability of operation;

8. The material of balance mechanism is made of high quality stainless steel. The surface of friction pair is quenched or sprayed with cemented carbide. It has good wear resistance and long service life;

9. Some models adopt first-stage double suction structure to improve anti-cavitation performance.

D/MD series products can reach GB/T 5657-20132 Technical specifications for centrifugal pumps (Ⅲ) standard; MD series products meet the MT/T 114-2005 "multistage centrifugal pumps for coal mine" standard, all MD series models have obtained the certificate of safety label of mine products issued by the National Mine Products Safety Mark Center for Safety Standard, seeing website: www.aqbz.org;

DF series products meet the GB/T5656-2008 Technical specifications for centrifugal pumps (II) standard;

The design, production and service processes of this product have a strict control system, which completely guarantees the product quality.
