Product Overview:

The KCB/2CY series gear oil transfer pump is suitable for transporting various oils with viscosity below 300 C.s.t, such as crude oil, diesel, lubricating oil, animal and vegetable oil, etc. Copper gears can be used to transport low flash point liquids such as gasoline, benzene, etc. The medium temperature shall not exceed 70 ℃, and the operating temperature of the high-temperature resistant oil pump shall not exceed 300 ℃. The pump itself is equipped with a safety valve, which provides safety protection in case of overload. There are three types of shaft seals: skeleton oil seal, mechanical seal, and packing seal. Please specify when ordering.

Product Features:

The KCB/2CY series gear oil transfer pump has a simple and compact structure, making it easy to use and maintain,
The KCB/2CY series gear oil transfer pump has good self-priming, which helps to prevent the need to inject liquid before each pump start,
The lubrication of KCB/2CY series gear oil pumps is automatically achieved by the liquid being transported, so there is no need to add additional lubricating fluid during daily operation.
4. Using an elastic coupling to transmit power can compensate for minor deviations caused during installation. When the pump is inevitably subjected to hydraulic shock during operation, it can play a significant buffering role.

Structure description:

The KCB/2CY series gear oil pump consists of components such as the pump body, gears, front and rear pump covers, safety valves, bearings, and sealing devices.
1. The gear oil pump, front and rear covers and other parts are made of gray cast iron, and 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
When the discharge valve is completely closed and high pressure and high pressure shock occur, the safety valve will automatically open, removing some or all of the high-pressure liquid back to the suction chamber, thereby 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. Type of inlet and outlet:
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 type oil transfer pump with waist flange with pipe threaded 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.
