2CY Gear Pump Application:

Suitable for conveying all kinds of lubricating liquid, the temperature is not higher than 70℃, if you need high temperature 200℃, with Shanghai Sunshine pump can be matched with high temperature resistant.materials, viscosity of 5×10-5 ~ 1.5×10-3m2/s.

Not suitable for conveying corrosive, containing hard particles or fiber, highly volatile or low flash point liquid, such as gasoline, stupid, etc.If transfer of chemical materials, please choose stainless steel gear pump. In addition to the configuration of ordinary motor, but also according to the user needs to configure the same specifications of explosion-proof motor.

2CY Gear Pump Instructions:

· Before starting gear pump, check whether the pump shaft rotates flexibly, whether there is any blockage, whether the valve on the inlet and outlet pipe is open, and whether the rotation direction of the pump is correct.
· A certain amount of lubricating fluid should be injected into the pump cavity before starting the pump that has not been used for a long time, in order to reduce the dry moraxella in the process of oil absorption and improve the self-priming performance of the pump.
· In case of abnormal noise or overheating after startup, stop and check immediately.

Seal and preheat

· Check whether there is leakage at the shaft end of the pump, such as: properly tighten the sealing cover of the packing seal, and disassemble the other seals for inspection.
· If the hot oil is transported, it should be preheated evenly when driving. Preheating is carried out by using the medium to be transported continuously through the pump body
· Preheating standard: The oil temperature of the suction inlet shall not be higher than the pump body temperature of 40°C. When the heating rate of preheating is controlled to be less than 40°C, the bolts fixed on the pump body shall be loosened during preheating and tightened after preheating.

• Model: NYP
• Type: high viscosity gear pump;
• Flow rate: 1-50 cubic meters/hour;
• Purpose: high viscosity pump;
• Viscosity range: 100-300000CST;
• NYP high viscosity gear pump structure: mainly internal and external rotor, shaft, pump body, front cover, bracket, seal, bearing and so on. Sealing has two forms of mechanical seal and packing seal, for high temperature, high viscosity and strong corrosive medium, choose packing seal. When conveying crystallizable materials, heat preservation jacket can be designed on the front cover and pump body, which can be melted by steam insulation during work. It rotates clockwise from the overhang end of the spindle to the pump. The structure of the high viscosity pump is more complex than the ordinary gear pump, do not disassemble maintenance, if there is a problem, please contact the manufacturer in time to help you solve.

Choose the advantages of high viscosity pump/nyp high viscosity gear pump:

1: Long life
2: pump smooth operation, not prone to failure, so that you in use to avoid unnecessary trouble and loss.
3: smooth conveying liquid, no pulsation, small vibration, low noise.
4: standard flange connection, only light pump head can be provided.
5: high viscosity gear pump speed and flow linear function relationship, can be appropriate to change the speed to change the flow of the pump. High viscosity pump is especially suitable for conveying high viscosity medium. High viscosity pump shaft end adopts mechanical seal.
6: Pay attention to the selection must be contacted with our factory sales staff and then selection, according to the viscosity to determine which type of pump.
