KCB, 2CY gear type fuel pump

1KCB, 2CY gear type fuel pumpProduct Structure and Images:

KCB and 2CY gear type oil transfer pumps are horizontal rotary pumps, mainly composed of pump body, gears, bearing seat, bearings, and sealing devices.
The pump body, bearing seat, etc. are made of gray cast iron, and the gears are made of high-quality carbon steel. Copper or stainless steel materials can also be used according to the special needs of users.
There is a packing chamber on the bearing seat, which plays an axial sealing role. 2CY100/3, 2CY150/3, 2CY150/3, KCB-300~960 pumps use skeleton sealing devices.
The bearing adopts a single row radial ball bearing. The KCB-18.3-83.3 gear type oil transfer pump consists of three oil resistant rubber rings and a retaining ring with a middle lining. The sealing degree is adjusted by adjusting the two nuts on the compression cover, and the bearings are copper based powder oil containing bearings. In addition, this series of pumps can all use flexible graphite with good elasticity, high and low temperature resistance, stable chemical properties, and self-lubricating properties as packing for sealing.
The pump is equipped with a safety valve. When the pump or discharge pipeline malfunctions or the discharge valve is accidentally completely closed, resulting in high pressure and high pressure shock, the safety valve will automatically open to discharge some or all of the high-pressure liquid back to the low-pressure chamber, thereby providing safety protection for the pump and pipeline.
Connect the drive motor directly with an elastic coupling and install it on a common cast iron chassis.

IIKCB, 2CY gear type fuel pumpProduct Features
KCB and 2CY gear type oil transfer pumps have simple and compact structures, making them easy to use and maintain.
The KCB and 2CY gear type oil transfer pumps in the series have good self-priming, which helps to prevent the need to inject liquid before each pump start.
The lubrication of KCB and 2CY gear type oil pumps is automatically achieved by the conveyed liquid, so there is no need to add additional lubricating fluid during daily operation.
The use of elastic couplings to transmit power can compensate for minor deviations caused during installation. When subjected to inevitable hydraulic impact during pump operation, it can provide improved buffering effect.

4KCB, 2CY gear type fuel pumpWorking principle
The KCB and 2CY gear type oil transfer pumps are equipped with a pair of rotating gears in the pump body, one active and one passive, which rely on the mutual meshing of the two gears to divide the entire working chamber inside the pump into two independent parts. A is the suction chamber for humans, and B is the discharge chamber. When the pump is running, the active gear drives the passive gear to rotate. When the teeth shift from meshing to disengagement, a local vacuum is formed on the suction side (A), and the liquid is introduced. The liquid sucked in fills the various tooth valleys of the gear and is carried to the discharge side (B). When the gear enters meshing, the liquid is squeezed out, forming high-pressure liquid and discharged outside the pump through the discharge port of the pump.

Usage description:
This pump is suitable for transporting various oils, such as heavy oil, diesel, lubricating oil, and can be used with copper gears to transport low point liquids, such as gas oil, benzene, etc. Our unit also produces stainless steel gear pumps that can transport beverages and corrosive liquids.
This pump is not suitable for those containing hard particles or fibers, and is suitable for viscosity of 5 * 10-5~1.5 * 103m2/s. The temperature is not high at 70 ° C. If you need to transport high-temperature liquids, please use a high-temperature resistant gear pump, which can transport liquids below 300 ° C.
