NYP type insulated high viscosity pump

schematic diagram

Overview
NYP seriesInternal gear pumpIt is a new type of positive displacement pump developed based on the needs of industries such as petroleum, chemical, coatings, oils, pharmaceuticals, dyes, and food. Due to its ability to use different materials and unique structure, this product is widely used for conveying media with different properties and viscosities.
Applicable medium temperature: -10 ℃ -200 ℃ (the applicable temperature for NYPO.78 and NYP2.3 is -10 ℃ -80 ℃).
Applicable medium viscosity: 1.0cSt -300000cSt (applicable viscosity for NYPO.78 and NYP2.3 is 1.0cSt -10000cSt).

advantage
(1) Smooth liquid transportation, no pulsation, low vibration, and low noise.
(2) Has strong self-priming performance.
(3) Proper selection of component materials can transport various corrosive media and can be used at temperatures up to 200 ℃.
(4) The inner and outer rotors have the same direction of rotation, with minimal wear and a long service life.
(5) The speed of the pump is linearly related to the flow rate, and the pump flow rate can be adjusted by changing the speed appropriately.
(6) Especially suitable for transporting high viscosity and thick media.

structural style(As shown in Figure 1)
(1) The working principle is that the driving gear (outer rotor) with internal teeth drives the inner rotor to rotate in the same direction inside the fully enclosed pump body. The crescent plate between the pump body and the front cover separates the suction and discharge ports. When rotating, negative pressure is formed at the suction port, and the liquid is sucked in. The rotor carries the liquid to the discharge port, and the pump body is discharged under pressure, completing the transportation of the liquid.
(2) The structure is shown in Figure 1. The pump mainly consists of inner and outer rotors, shaft, pump body, front cover, trailer, seal, bearings, etc. There are two forms of seals: mechanical seals and packing seals. For media with high temperature, high viscosity, and strong corrosiveness, packing seals are preferred. When conveying materials that are prone to crystallization, insulation jackets can be designed on the front cover and pump body, which can be melted by steam insulation during operation. The pump can be equipped with a safety valve. When the pump or pipeline system is overpressure, the safety valve opens to form internal backflow, ensuring system safety. The pump device consists of a pump, a motor, and a base. There are two types of transmission modes: bridge type and direct connection type. When viewed from the extended end of the main shaft towards the pump, it rotates clockwise.

Main considerations when selecting a pump
(1) The lubricity, cleanliness, and corrosiveness of the medium.
(2) The viscosity and temperature of the medium.
(3) Pump inlet pressure and outlet pressure, installation height.
(4) Explosion proof requirements for usage scenarios.
(5) Please specify the pump model, design pressure, speed, medium viscosity, temperature, motor explosion-proof level, and medium name when placing an order.
(6) For special operating conditions other than those listed in this sample, they can be designed and supplied separately according to user requirements.
