Quantity

Designed to meet industrial, agricultural, and marine demands for efficient fluid transfer, cast iron gear pumps deliver robust performance in challenging environments. Combining precision-engineered gears with a durable cast iron body and adaptable sealing systems, these gear oil transfer pumps excel in handling medium-to-low viscosity fluids such as hydraulic oils, fuels, and irrigation liquids. Ideal for applications like hydraulic systems, fuel distribution, and agricultural machinery, gear fluid oil pumps ensure clog-resistant operation, extended service life, and energy-efficient fluid management. PWS’s horizontal design prioritizes stability and ease of maintenance, making it a reliable solution for long-term, low-waste operations.

Core Advantages

High Efficiency:
The design of the gear pumps makes it have low energy loss and high efficiency when conveying fluids, and is suitable for occasions that require efficient conveying.
Gear Transmission:
The fluid is sucked in and discharged through the rotation of a pair of meshing gears, with a simple structure and high transmission efficiency.
Sealing Design:
Usually equipped with mechanical seals or packing seals to ensure the sealing reliability of the pump under high pressure or high temperature conditions and reduce the risk of leakage.

Precision engineering

High precision gear processing

Gears are made of 304/316 stainless steel or tungsten carbide, precision machined to minimize backlash, reduce internal leakage by 40%, and significantly increase volumetric efficiency to ensure conveying accuracy and energy efficiency.

Horizontal compact structure

Horizontal mounting of the pump body saves space, and the horizontal layout of the inlet and outlet simplifies piping connections and reduces elbow losses, especially suitable for narrow equipment compartments or mobile device integration.

Multiple seal adaptations

Seal ring: suitable for conventional oil and low corrosive media;
Combined seals: high pressure and temperature resistant, suitable for hydraulic systems;
Gap seals: non-contact design, designed for high viscosity or micro-particulate media.

The technical parameters of PWS Horizontal Cast Iron Gear Pump cover core indicators such as flow range, pressure rating, motor power and speed. At the same time, relying on key components such as cast iron pump body, high-precision gear pair, wear-resistant shaft sleeve and combined sealing structure, it ensures low leakage and long life operation when transporting lubricating oil, hydraulic oil and other media, and meets the strict requirements of industrial equipment for oil pressurization, circulation and metering. It has become an ideal choice for oil transportation in fields such as mechanical manufacturing and petrochemicals.

PWS gear pumps are widely used in the treatment of lubricating oil, hydraulic oil and other media due to their stable volumetric conveying characteristics. Gear oil transfer pumps and gear fluid oil pumps are typical branches of these pumps, which achieve efficient and low pulsation fluid transfer through precision designed components. The core components of this type of pump include high-strength cast iron pump body, precision meshing gear pair (driving gear and driven gear), wear-resistant shaft sleeve, bimetallic sliding bearing, floating side plate and combined sealing structure. Each component is optimized for material matching (such as cast iron shell, tungsten carbide sealing surface) and process accuracy (such as gear clearance control) to ensure low leakage and long life operation under high pressure and high viscosity conditions, while meeting the requirements of zero medium pollution, low noise and easy maintenance. It has become a key equipment for oil transportation in fields such as petrochemicals and mechanical manufacturing.

The installation of the Horizontal Cast Iron Gear Pumps requires a series of rigorous steps to ensure stable operation of the equipment. Firstly, before installation, it is necessary to disconnect the power supply, clean the oil stains, and make sufficient preparations. Next, carry out disassembly work, such as removing the timing belt, crankshaft timing pulley, and related brackets. This step requires extra caution to prevent additional damage caused by improper operation.
When installing a new gear pumps, it is necessary to ensure that the oil pressure is normal and the timing is correct. This requires a certain understanding of the internal structure of the engine, and professional assistance can be sought if necessary. Different types of engines have their own specific replacement processes, and it is essential to strictly follow the procedures.

In industrial lubrication and oil transfer systems, the gear oil transfer pump serves as the core power unit, and its performance curve is a key basis for evaluating the pump's operating efficiency, stability, and applicability. As a typical representative of this type of pump, the performance curve of the Horizontal Cast Iron Gear Pump can determine the optimal working point, efficient operating range, and adaptability to medium viscosity and pressure changes through flow head (Q-H), providing scientific selection basis for the transportation of lubricating oil, hydraulic oil and other media, ensuring efficient and stable oil circulation of the equipment in industrial applications.
