2024-07

NORD pump

01. When conveying viscous or solid materials, it has high efficiency, can pass large-size materials, and has little shear on materials.
02. Optimize the three-blade spiral rotor, run smoothly without pulsation, and be more efficient and energy-saving. Compared to the centrifugal pump can save energy 15% 40%
03, 10-650r/min low speed design is less wear-resistant, and the moving parts are made of more wear-resistant materials with special laser hardening treatment.
04. Within the allowable range, the viscosity of the medium or the viscosity change during operation has no effect on the operation and performance of the pump.
05. There will be no shortage of effective cavitation margin NPSH, etc., and it can be mixed with gas and liquid, and there is no requirement for the gas-liquid mixing ratio of the fluid.

Centrifugal pump

1, can not completely transport viscous, solid fluid, otherwise easy to block, and cause serious shearing and crushing of the material.
02. Due to the high speed of the centrifugal pump, the pulsation during operation is large, the vibration is severe, the noise is large, the energy consumption is large, and the probability of failure is increased.
03. Speed-generally running at a high speed of 1500r/min or even higher increases the number of friction per unit time and is more likely to wear.
04, can not fully meet the transport of viscosity medium, once the medium viscosity changes, flow and pressure changes sharply.
05. When the gas enters and the actual working condition point deviates from the best working condition by 10% or more, the pump shaft will distort and the pump body will vibrate or even cavitation.
