 Suofu steam generator water pump features


 High and low temperature resistance

The temperature resistance of NP series steam generator water pump is between -120~150 °C

 

 High pressure resistance

NP series miniature magnetic gear pump adopts magnetic drive design, the whole pump has no moving seal, only O-ring static seal, there is no risk of dynamic seal failure. NP series special cavity profile design, can adapt to the outlet pressure wide range of changing conditions, whether it is low pressure, high pressure or short time reversal can be well adapted.

42 series steam generator water pump: inlet and outlet pressure difference up to 20Bar; Pump body pressure resistance up to 30Bar-100bar (customized)   

51/60/98/106 series steam generator water pump: the pressure difference between inlet and outlet can reach more than 40-50Bar; The pump body can withstand pressures up to 70 bar


 Abrasion resistant

The gear used in the NP series steam generator pump is made of PEEK engineering plastic with high-performance special filling material, and the working tooth surface adopts high-precision one-time injection molding process without mechanical processing. The process of one-time injection molding greatly increases the process difficulty and manufacturing cost, but ensures the complete and dense structure of the gear working surface and improves the wear resistance and life of the gear.

The high-precision industrial zirconia ceramic shaft used in NP series steam generator water pump has super wear resistance and rigidity, which ensures the stability of pump work under abrasive liquid and high pressure working conditions and improves the life of the product.

The special gear profile design of Sofu's patented technology provides excellent wear resistance to the gears of the steam generator pump, and the almost pure rolling gear meshing feature minimizes wear during gear operation.


 Corrosion resistant

NP series steam generator pump all series are Sofu's independent patented technology products, according to different working conditions can be customized steam generator pump of different materials to meet the use of steam generator pump in different systems.

Pump body material: 316L stainless steel / Hastelloy alloy / titanium alloy / other types of alloys / PEEK polymer material [high strength, corrosion resistance, wide temperature range]

Bearing/gear material: PEEK engineering plastic with high-performance special filler material (one-time injection molding) [Excellent self-lubrication, mechanical properties, corrosion resistance and wear resistance, enhance the adaptability of the pump and improve the service life of the product. 】

Shaft material: high-precision industrial zirconia ceramics [high-precision zirconia ceramics have extremely high wear resistance, oxidation resistance, high strength, high hardness, high temperature resistance, corrosion resistance, light weight and other advantages, is an excellent gear shaft material. 】

Magnetic drive material: PPS or PVDF plastic fully coated rare earth magnet [PPS plastic fully coated 150°C high temperature rare earth magnetic drive is used to transmit continuous and powerful torque to the pump. 】

Sealing ring material: fluoroelastomer (FKM) / ethylene propylene diene rubber (EPDM) / Teflon (PTFE) / fluorosilicone rubber (FVMQ) / neoprene (CR) / PTFE energy storage sealing ring [A variety of materials are optional, adapt to a variety of corrosive liquids, greatly reducing the risk of leakage. 】

 

 No leakage in magnetic transmission

NP series steam generator water pump products use magnetic couplings, which eliminate the risk of leakage and maintenance costs caused by traditional dynamic seals.

 

 Low noise

At 2000rpm, the noise of NP series steam generator pump products is between 45dB~75dB.

Helical gears can be used for applications with high noise requirements.


 Strong self-suction

In the case of full dry operation, the self-priming height of the inlet of the NP series steam generator pump can reach 4 meters, and the vertical suction height is 8.2 meters.


 Long service life

In the clean medium, the NP series steam generator water pump can be used for more than 20,000 hours


 Can run dry for a long time

In many applications where self-priming is required, it is of no practical use if the pump can only run dry for a short time. The dry running time of imported pumps of the same type is very short, generally measured in seconds or minutes, and the dry running time of NP series products can reach 100 hours at the appropriate speed.

In applications where the inlet vacuum of the pump is used to draw media into the pump, the NP Series provides reliable dry running performance without damage due to dry operation during self-priming.


 The outlet pressure difference is stable and pulsation-free

Compared with piston and diaphragm steam generator pumps, NP series magnetic gear pumps have stable flow and no pulsation, which can easily form a closed-loop control system with various flow meters.
