A high-quality, tandem (twin-section) hydraulic gear pump, manufactured by the renowned company PARKER, an OEM supplier. It is the "heart" of the hydraulic system, responsible for generating the oil pressure that powers all of the machine's working functions. Precision construction and durable materials guarantee the maintenance of factory pressure and flow parameters, which translates into the full power and speed of the hydraulics.
OEM quality product – a guarantee of a perfect fit and parameters identical to the original.

Before replacing the pump, you must completely depressurize the hydraulic system by lowering all attachments to the ground and operating all levers with the engine off. Hot hydraulic oil can cause severe burns.
The hydraulic pump is the key component that generates the machine's power. Its wear leads to a drop in pressure, which manifests as a lack of force, slow operation, and overheating of the oil. A pump failure immobilizes the entire machine.
A worn pump means an immobilized machine and costly downtime.
Shrapnel from a worn pump contaminates the entire system, destroying valves and rams. The cost of a new pump is negligible compared to a full hydraulic system overhaul. Don't take the risk – order a new, reliable PARKER pump and restore your machine's full power and efficiency.

This is a tandem pump. In simple terms, one section with a higher displacement supplies the main working functions (e.g., the backhoe arm), while the smaller section can supply, for example, the power steering system or other auxiliary circuits. This allows for independent and stable operation of all systems.
2. How do I check if the pump is worn out?The best method is to measure the pressure and oil flow using specialized equipment (a pressure gauge and flow meter), according to the service manual. Significantly lower parameters than nominal values indicate pump wear.
3. I found metal filings in the hydraulic filter. What does that mean?Metal filings in the filter are a sign of a serious mechanical failure within the system. They most often come from a disintegrating hydraulic pump. In this case, you should stop work immediately and perform an overhaul to avoid contaminating and destroying the entire system.
