product overview

1. This pump is suitable for transporting various lubricating liquids with a temperature not exceeding 70 ℃. If a high temperature of 200 ℃ is required, contact our unit and use high-temperature resistant materials with a viscosity of 5 × 10-5~1.5 × 10-3m2/s.

2. This pump is not suitable for transporting corrosive, hard particle or fiber containing, highly volatile or low flash point liquids such as gasoline, benzene, etc.

This type of pump is equipped with a pair of rotary gears in the pump body, which rely on the mutual meshing of the two gears to divide the entire working chamber inside the pump into two independent parts. When the pump is running, the active gear drives the passive gear to rotate. When the gear disengages, a local vacuum is formed on the suction side, and the liquid is sucked in. The liquid sucked in fills the various tooth valleys of the gear and is carried to the discharge side. When the single-stage single suction oil pump gear enters meshing, the liquid is squeezed out and discharged from the pump.

Structure description:

This product consists of components such as pump body, gears, front and rear pump covers, safety valves, bearings, and sealing devices.

1. The pump body, front and rear covers, and other parts are made of gray cast iron, while the gears are made of high-quality carbon steel; It can also be made of copper or stainless steel according to user needs.

2. Safety valve.

The 2CY series gear lubrication pump does not come with a safety valve, and users need to install a safety valve in the pipeline system themselves when using it. The KCB, 2CY series gear type oil transfer pump is equipped with a safety valve above the rear pump cover or pump body. When the pump or discharge pipeline fails or the discharge valve is completely closed, high pressure and high pressure may occur? When hit, the safety valve will automatically open, removing some or all of the high-pressure liquid back to the suction chamber, thus providing safety protection for the pump and pipeline.

3. Bearings.

2CY series gear lubrication pumps all use DU bearings; Tin bronze bearings can be used according to user requirements& 0818.3-83.3, 2CY1.1 gear type oil transfer pump adopts DU bearings; Tin bronze bearings can be used according to user requirements.

KCB133-960 and 2CY8-60 gear type oil transfer pumps have three structures: DU bearings, tin bronze bearings, and rolling bearings, which need to be specified when ordering. Any items not specified during ordering shall be supplied according to the DU bearing structure.

The bearing is of built-in type and relies on the conveyed medium for lubrication; 011 bearings and tin bronze bearings can operate in non lubricating media.

4. Shaft seal.

The shaft end seals of this series of products have three structures: skeleton oil seals, mechanical seals, and packing seals.

a. Skeleton oil seal: The characteristics of skeleton oil seal are easy maintenance and replacement, low cost, but short service life. Ding Qing rubber skeleton oil seal is suitable for 1001: the following working environments; Fluororubber skeleton oil seal is suitable for working environments below 200 ℃.
b. 1. Mechanical seal: The characteristics of mechanical seals are reliable sealing, long service life, and high cost. The substrate of the mechanical seal is made of stainless steel, and the dynamic and static surrounding media are made of YG8 hard alloy or YG8 graphite, respectively. The operating temperature is below 200 ℃.
c. Packing seal: Packing seal is only used for high-temperature oil pumps, and its characteristic is high temperature resistance with a small amount of leakage. During use, regular adjustments should be made according to the leakage situation, and the operating temperature should be below 250 ℃.

The type of sealing structure required by the user should be specified when ordering. Any items not specified at the time of ordering shall be supplied according to the nitrile rubber skeleton oil seal structure.

5. Inlet and outlet type.

The inlet and outlet of the 2CY series gear lubrication pump are designed with British pipe threads (G) corresponding to the diameter, which are directly made on the pump body.

KCB18.3-200, 2CY1.1-12 gear oil transfer pump with pipe screw? Waist flange of mouth; Other pumps do not come with flanges. When users need flanges, they should be specified in the order.

6. The pump and motor are connected by an elastic coupling and installed on a common chassis.
