First, the product overview

DFLPH vertical chemical shield pump is vertical pipeline chemical shield pump, which is mainly composed of pump body, impeller, shielded motor and so on. It adopts new static seal structure to prevent water dripping and ensure the working environment is not contaminated. It is mainly used in petroleum, Chemical, textile printing and dyeing , pharmaceuticals, food, metallurgy , power plants and atomic transport corrosive media and have special requirements of the media. Product implementation of GB / T5656-1994 " centrifugal pump technical conditions (II)" standard.

Second, the product features

1, energy-efficient: The CFD computational fluid dynamics, analysis and calculation of the pump pressure distribution and velocity distribution, optimize the pump flow channel design to ensure that the pump has an efficient hydraulic shape line to improve the efficiency of the pump;

2, Static seal structure: The motor is a shielded motor, no seal, so that the drip does not leak, to ensure that the work environment is not contaminated;

3, low noise: static noise design method to reduce noise pollution, noise than the average pipeline pump 3 to 5% lower;

4, easy installation and maintenance: pipeline design, import and export of the same caliber and in a straight line, easy installation and maintenance, routine maintenance is very simple;

5, the whole machine performance is good: the use of advanced dual throttling ring balance method, axial force balance effect, effectively reduce the motor failure rate and improve the reliability of operation; balance of high precision rotor balancing accuracy grade G1.0;

6, casting process new: DFLPH pump over-current components (such as the pump body, impeller, pump cover, seal ring, etc.), using silicone melt precision casting, flow channel size and stability, Of the attachment, to retain the nature of the metal, will not affect the delivery of casting attachment material.

7, explosion-proof structure: Motor for the explosion-proof motor, suitable for all types of flammable, explosive media delivery occasions.
