Product Overview

The KCB-type high-temperature and high-pressure stainless steel gear oil pump is suitable for conveying heavy oils, diesel oil, mechanical oils, vegetable oils, and other liquids with lubricating properties similar to those of lubricants—provided that the medium’s viscosity does not exceed 150 mm²/s, the temperature does not exceed 120°C, and the medium is non-corrosive and free from hard particulate impurities and fibers. The KCB gear oil pump is primarily used in industries such as petroleum, chemical engineering, metallurgy, mining, and power plants for the transfer and pressurization of oil-based media, fuel injection, and the delivery of lubricating oils in large-scale mechanical equipment lubrication systems. It can also handle non-lubricating oils, beverages, and low-corrosive liquids. When equipped with copper gears, this pump can convey low-flashpoint liquids such as gasoline and benzene. In addition to being fitted with standard motors, this series of stainless steel pumps can also be configured with explosion-proof motors of the same specifications according to customer requirements.

Meaning of KCB Type High-Temperature Gear Oil Pump Model

Application Scope of KCB High-Temperature and High-Pressure Stainless Steel Gear Oil Pump

The KCB-type high-temperature gear oil pump is primarily used for large-volume oil transfer and unloading in oilfields, oil storage facilities, ports, terminals, ships, and other similar applications. It is suitable for conveying various types of oils, including heavy oil, diesel, and lubricating oils. When paired with copper gears, it can also handle low-viscosity liquids such as gasoline and benzene. Stainless steel gear oil pumps can be used to convey beverages and corrosive liquids. This gear pump is not suitable for fluids containing hard particles or fibers. Its applicable viscosity range is from 5×10⁻⁵ to 1.5×10³ m²/s. The operating temperature should not exceed 70℃. If you need to pump high-temperature liquids, please use the KCB high-temperature-resistant gear pump, which can handle liquids up to 300℃.

Can be used as a transfer and booster pump in oil transmission systems;

A fuel pump that can be used for fuel delivery, pressurization, and injection in the fuel system;

In a hydraulic transmission system, it can serve as a hydraulic pump to provide hydraulic power.

In the industrial sector, it can be used as a lubricating oil pump.

Working Principle and Structural Features of the KCB High-Temperature, High-Pressure Stainless Steel Gear Oil Pump

Structural Diagram of the KCB High-Pressure Gear Oil Pump

The KCB-type stainless steel gear oil pump features a pair of rotating gears—one driven and one driven—installed within the pump housing. By means of the meshing engagement between these two gears, the pump’s working chamber is divided into two independent sections: the suction chamber and the discharge chamber. As the pump operates, the driving gear rotates and drives the driven gear. When the gear teeth transition from meshing to disengaging on the suction side, a local vacuum is created, drawing liquid into the pump. The liquid drawn in fills the tooth spaces of the gears and is carried to the discharge side. As the gears re-engage, the liquid is squeezed out, forming high-pressure fluid that is discharged through the pump’s outlet.

Structural features:

The KCB high-pressure gear oil pump consists of several key components, including the main pump body, front and rear pump covers, gears, driving and driven shafts, bearings, a relief valve, and shaft-end seals. The gears undergo heat treatment to achieve high hardness and strength; they are mounted together with the shafts inside replaceable bushings for smooth operation. All parts within the pump are automatically lubricated during operation by utilizing the pumped medium itself. The entire series of gear oil pumps is equipped with an oil pump unit comprising a three-claw flexible coupling connected to an electric motor. This series of gear oil pumps features a simple and compact design, is easy to install and maintain, operates smoothly, and boasts reliable performance.

The high-pressure gear pump features reasonably designed oil-leakage and oil-return grooves, which minimize the torque load on the gears during operation. As a result, the bearing load is reduced, wear is minimized, and the pump efficiency is high.

The high-temperature gear pump is equipped with a valve as an overload protection device. The valve’s full-return pressure is 1.5 times the pump’s rated discharge pressure; it can also be adjusted separately within the allowable discharge pressure range according to actual needs. However, please note that this valve is not suitable for long-term operation as a pressure-reducing valve. If such function is required, a separate pressure-reducing valve should be installed on the pipeline.

Viewed from the extended end of the main shaft, the rotation is clockwise.

What is your typical delivery time?

Models in stock can be shipped the next day at the latest. All others are custom-made, with lead times generally ranging from 7 to 90 days depending on the product size and project specifics. Please contact our sales manager for details: 0731-88632200 。

Do you have centrifugal pumps in stock?

Centrifugal pumps come in numerous models and configurations. Except for a small number of high-volume, standard models that are in stock, the vast majority are not stocked and are customized products. We need to select a pump based on your site's flow rate, head, media temperature, pH value, and installation conditions, etc., to determine the pump model and configuration before we can submit an order to the factory for production.

What information should I provide when requesting a quote?

Generally, to obtain an accurate quotation, we recommend providing us with the following information: pump flow rate, head, on-site operating voltage and frequency, temperature, pH value, and solid particle content of the fluid being conveyed, and on-site installation conditions (horizontal or vertical installation), etc.

If you are not sure, don't worry, our business managers will assist you in determining this.

What products do you mainly produce?

Zhonglian Pump Industry manufactures various large industrial centrifugal pumps. Main products include: self-balancing multi-stage pumps, multi-stage centrifugal pumps, single-stage centrifugal pumps, split-case pumps, chemical pumps, submersible pumps, pipeline pumps, long-shaft pumps, condensate pumps, etc.

Could you help me with the selection?

Certainly! If the water pump model is not selected accurately, there will be big problems. If you choose a smaller one, it won't meet your needs; if you choose a larger one, it will waste electricity and fuel, increasing your costs.

Why is it so slow to get a price quote?

Because centrifugal pumps are non-standard customized products with many models, the price range is also very large. Even for the same model, the price difference is also very large due to different materials and configurations. Taking the most common water pump accessory—the impeller—as an example, the price of a stainless steel impeller is several times that of a cast iron impeller. Therefore, we need to clarify the relevant information to give you an accurate price. Normally, if you provide relatively comprehensive information, we can quote within 5 minutes.
