NYP Inner Ring Rotary Pump

NYP internal mesh high viscosity rotor pump is suitable for transporting high viscosity and viscous media, and is applied in various fluid transportation industries
The materials of NYP inner ring rotary pump are cast iron and stainless steel
The pump head, pump housing, and sealing chamber can all be equipped with insulation jackets Choose the necessary insulation location based on practical necessity
The jacket and pump body are cast as one, with excellent insulation results, which can roughly prevent various problems caused by welding jacket incubation
When heating is required: insulation can be achieved by introducing various heat media such as hot steam and thermal oil into the jacket cavity
When cooling is required: Various cooling liquids can be used to connect the constant temperature of the pump body
Adjustable clearance: The pump can adjust the gear clearance based on viscosity without disassembling the pump, meeting the process requirements of the pump at different viscosities
The outer rotor mobilizes the inner rotor to rotate in the same direction, with minimal wear and a long service life
Application industry: Suitable for transporting pure and viscous fluids, and can be used to transport oil products such as lubricants, crude oil, etc; It can also be used to transport high viscosity materials such as molasses, polyurethane, good and bad materials, rubber, asphalt, paint, adhesives, dyes, coatings, lubricants, polyols, food, pharmaceuticals, etc. that do not contain particulate impurities; It can also be used to transport high-temperature, high viscosity polymer melt materials such as PA PB, PC PE PS HIPS, ABS, PP, PET, PVA, etc
Applicable medium temperature: -10 ℃ -200 ℃
Applicable medium viscosity: 1.0cSt -300000cSt

Structural characteristics of NYP internal gear pump
(1) Working principle
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 on the pump body and 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) Structure
The pump is mainly composed of inner and outer rotors, shaft, pump body, front cover, seal, bearings, etc. There are two forms of seals: mechanical seals and packing seals (for special requirements, magnetic drive and zero leakage structure can be selected). For media with high temperature, high viscosity, and strong corrosiveness, packing seals are selected.
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 motor end towards the pump, it rotates clockwise.
