Product Description

90R075 90L075 Series Hydraulic Pump And Parts OVERVIEW

The 90R075 and 90L075 are 75cc swash plate variable axial piston pumps specially designed for closed hydrostatic drive systems. Built with an integrated charge pump, they deliver makeup oil, cooling flow and control pressure for displacement adjustment, supporting stable bidirectional operation.
With high power density and excellent pressure resistance, these pumps run reliably under heavy loads. We supply a full range of interchangeable replacement parts, including cylinder blocks, piston sets, swash plates, retainer plates, drive shafts and seal kits, to extend pump service life. Widely applied in concrete mixers, agricultural tractors, loaders and other construction machinery.

90R075 90L075 Series Hydraulic Pump And Parts FAQ:


1. What is the 90R075 90L075 Series Hydraulic Pump And Parts ?


The 90R075 & 90L075 series are 75cc swash plate variable axial piston pumps designed for closed hydrostatic drive systems.90R075 stands for right rotation, while 90L075 is left rotation. Each pump integrates a built-in charge pump to supply makeup oil, cooling flow and control pressure for displacement adjustment.
We provide full interchangeable spare parts for overhaul, including cylinder blocks, piston sets, swash plates, retainer plates, drive shafts, seal kits and charge pump components. Widely fitted on concrete mixers, tractors, loaders, harvesters and sanitation engineering vehicles.


2. What makes the 90R075 90L075 Series Hydraulic Pump And Parts ?


  • Reliable swash plate variable displacement structure with built-in integrated charge pump for oil replenishment, cooling and hydraulic control.

  • High-hardness wear-resistant core parts (piston sets, swash plates, cylinder blocks) for long service life under heavy loads.

  • Two rotation options: 90R075 right rotation & 90L075 left rotation to fit diverse equipment layouts.

  • Complete matching interchangeable spare parts support full pump overhaul and quick on-site maintenance.

  • Compact high-power design, stable performance for agricultural, construction and sanitation machinery closed hydraulic circuits.

3. What is the working pressure range of 90R075 90L075 Series Hydraulic Pump And Parts ?


  • The high-pressure side rated working pressure of 90R075 and 90L075 pumps can reach up to 42 MPa.

  • The built-in charge pump maintains a low control pressure of around 1.8–2.5 MPa to supply displacement adjustment, system oil makeup and cooling flow.

  • All matching spare parts are manufactured to withstand this full pressure range for stable heavy-duty operation.


4. Can 90R075 90L075 Series Hydraulic Pump And Parts replace other brands?


Yes, our 90R075 & 90L075 hydraulic pumps and matching spare parts are fully interchangeable with the original 75cc closed-circuit piston pumps of the same model specification.They adopt identical installation dimensions, internal structure and pressure parameters, which can directly replace mainstream original brand pumps without modifying equipment.All core replacement parts like cylinder blocks, piston sets and swash plates perfectly fit the original pump housing for easy overhaul.

5. What hydraulic oil is recommended for 90R075 90L075 Series Hydraulic Pump And Parts ?


  • Recommended oil type: Anti-wear hydraulic oil (AW hydraulic oil) with good anti-oxidation, anti-rust and anti-wear properties.

  • Viscosity grade: ISO VG 46 is the standard choice for most working environments; ISO VG 32 for low-temperature areas, ISO VG 68 for high-temperature heavy-load conditions.

  • Requirements: Use clean oil with filtration accuracy ≤ 10μm, avoid mixed use of different oil brands.


6. What is the typical speed range of 90R075 90L075 Series Hydraulic Pump And Parts ?


  • The standard rated input speed of the 90R075 and 90L075 hydraulic pumps is 2200 rpm.
    The continuous working speed range is 500–2400 rpm.
    Short-time peak speed can reach 2600 rpm, but long-term operation over 2400 rpm will accelerate wear of internal parts like piston sets and swash plates.


7. Do you provide OEM or customized services?

  • Yes, we support OEM and customized services for the 90R075 & 90L075 series hydraulic pumps and spare parts.
  • OEM service: We can print your brand logo, mark custom part numbers and outer packaging according to your requirements.
