Hydraulic Gear Pump Repairs

Hydraulic gear pump repairs, hydraulic piston pump repairs, and hydraulic vane pump repairs are the three most common types of hydraulic pump repairs, among the gear pump is the simplest and most economical type of hydraulic rotary pump. Gear pumps utilize a mesh of two or more gears that displace fluid within an internal cavity.

When the fluid is contaminated, the gear pump may be worn and needs to be repaired.

Elephant Fluid Power has been engaged in hydraulic pump repairs for many years. It has rich experience in hydraulic gear pumps repair and sufficient repair parts. Elephant Fluid Power mainly examines the following aspects to determine the cause of gear pump problems and how to the gear pump repairs:

1. Enclosure seal inspection

When we perform hydraulic gear pump repairs, we inspect the housing seals, and if the housing seals are cracked or dry, replace the worn or leaking seals as needed. Elephant Fluid Power has spare parts for hydraulic seals of major hydraulic brands.

2. Drive and idler

In a gear pump, there are two sets of gears, the gear that drives the pump and the gear that is driven. The rotor or drive gear drives the movement, while the idler gear is driven. Since these gears provide power to the pump, failure of any of these two gears will hinder the function of the pump, requiring immediate repair of the hydraulic gear pump

3. Pressure port inspection

The high-pressure and low-pressure ports in hydraulic gear pumps have different functions, and failures can disrupt the delicate pressure balance and make it ineffective. Elephant Fluid Power checks the pressure port to determine whether the pressure port needs to be replaced and repaired.

4. Bushing inspection

Too much pressure in the gear pump will cause lubrication loss and excessive wear of the bushing supporting the gear journal. When the bushing fails to work, it may cause inefficiency or pump failure. When the bushing is contaminated and worn, it needs to be replaced in time.

5. Oil seal inspection

The oil seal is used to prevent oil and grease from leaking between the shaft and the bearing housing. Worn or cracked oil seals can cause oil leakage, which affects the efficiency of the gear pump. It also allows contaminants such as dirt and debris to enter the pump and collect on the shaft and bearings, causing damage. We provide various types of oil seal spare parts with timely delivery.

6. Shaft inspection

Excessive torque inside the gear pump rotor can cause the shaft to bend, break or shift by itself, and may shear the screws. Damage or displacement of the shaft will eventually lead to housing wear, head wear and eventual rotor damage.

7. Bearings inspection

The bearings in a gear pump are necessary to reduce friction and ensure smooth operation. Worn-out bearings can increase friction and stress on gear pump components and cause the pump to lose its ability to generate pressure and operate effectively. They may also cause the pump to consume excessive amounts of energy.
