Product Description
The GP gear pump is professional equipment for pumping viscous fluids: engine and transmission oils, diesel fuel, hydraulic fluids, antifreezes, greases, and other high-viscosity technical fluids.
The operating principle of the GP pump is based on the use of a pair of gears (driving and driven), which, when rotating, create a vacuum at the inlet and pressure at the outlet. This design ensures a stable fluid supply without pulsations, high efficiency when working with viscous media, and a long service life.
GP pumps are available in several modifications: with electric drive (220V, 12V, 24V) and manual drive. Electric models are equipped with reliable motors with overload protection, while manual ones feature an ergonomic handle with a smooth stroke.
The pump housing is made of cast iron or aluminum alloy, and the working gears are made of hardened steel or bronze. This design provides wear resistance and the ability to work with abrasive impurities.
Key advantages of the GP model:
- High-viscosity fluid handling – efficiently pumps oils with a viscosity of up to 10,000 CPS;
- Stable supply – uniform flow without pulsations due to the gear design;
- High efficiency – minimal power loss during pumping;
- Reliability – simple design with a minimum number of wearing parts;
- Versatility – suitable for fuel, oils, hydraulic fluids, greases;
- Durability – service life of up to 5,000 hours without major repairs.

Application Instructions
The GP gear pump is designed for pumping engine and transmission oils, hydraulic fluids, diesel fuel, antifreezes, medium-viscosity greases, and other technical fluids.
- Preparation: Install the pump on a stable surface or secure it to a container. Check the reliability of the mounting and the absence of damage to the housing, hoses, and electrical connections.
- Hose connection: Connect the suction hose to the pump inlet (marked “IN”), and the discharge hose to the outlet (marked “OUT”). Ensure the connections are tight and leak-proof.
- System priming: During the first start-up or after a long downtime, pour a small amount of the pumped fluid into the suction hose to remove air and create initial prime.
- Start-up: For electric models – turn on the power; for manual models – start turning the handle smoothly. Let the pump run for 10-15 seconds to fill the system.
- Pumping: Open the valve or press the trigger of the dispensing gun. Monitor the pumping process, and do not allow the pump to run “dry” (without fluid).
- Completion of work: Close the valve, turn off the pump. When pumping oils and viscous fluids, it is recommended to briefly run the pump in reverse (if such a function is provided) to relieve pressure in the hoses.
Safety precautions:
- Do not use the pump to pump acids, alkalis, aggressive chemicals, and solvents incompatible with the seal materials.
- Running the pump without fluid (“dry”) for more than 30 seconds is prohibited – this leads to overheating and gear damage.
- When working with electric models, ensure reliable grounding and protect the electric motor from moisture.
- Do not exceed the maximum viscosity of the pumped fluid (10,000 CPS) – this can lead to motor overload.
- The temperature of the pumped fluid must not exceed +60°C (for standard seals) or +120°C (for heat-resistant seals).
- Regularly check the condition of hoses and connections – if cracks or leaks are found, immediately replace the damaged elements.
- During prolonged downtime (more than 1 month), drain the remaining fluid and preserve the pump by lubricating the working surfaces with compatible oil.
Maintenance and Repair
The GP gear pump requires minimal maintenance:
- Daily: Visual inspection for leaks, checking fasteners.
- Monthly: Checking the condition of hoses and seals, lubricating moving parts (for manual models).
- Quarterly: Replacing seals if signs of wear appear, checking gear clearances.
- Annually: Preventive maintenance with replacement of worn parts.
All spare parts (gears, seals, bearings) are available in stock. The average service life of the pump, subject to operating conditions, is 5-7 years.
