White House Products Ltd - Hydraulic Pump Supplier

On-Site Engineering Capabilities


White House Products Ltd possesses a wide range of on-site engineering, simulation, and testing facilities to assist our customers who are searching for comprehensive hydraulic manufacturing services. We offer computer-aided design (CAD) services, a hydraulic engineering workshop outfitted with state-of-the-art gear, and testing facilities for hydraulic equipment.

Below you will find an outline of some of our engineering services:

Computer-aided capabilities:

We strive to stay at the forefront of modern hydraulic solutions, using the latest technologies to serve the needs of our customers. One such technology we use is computer-aided design (CAD), which offers precise and intricate design capabilities. Through this technology, designing components of a hydraulic system, such as hydraulic motors and various other parts, is remarkably efficient and accurate.

Whether you need a unique design for hydraulic hose assemblies or want to understand the details of pneumatic equipment in a system, our CAD services allow us to model, analyse, and refine designs before manufacturing begins. This not only enhances accuracy but also reduces costs by minimising errors.

Our capabilities include:

  • A full Autodesk 3D CAD suite of programs allowing the creation of 3D models, renders, and fully dimensioned orthographic drawings of hydraulic components.
  • Simulators to demonstrate effects of deflection, stresses, and more on a particular component or assembly.
  • A fluid power simulation package; allowing us to view the operation of new hydraulic circuits before supply and produce schematic diagrams.

Engineering workshop facilities:

Our facilities, equipped with everything from advanced welding equipment to precision milling machines, stand ready to deliver both standard and non-standard hydraulic parts and components. Need bespoke hydraulic solutions? Our design and fabrication expertise allows us to produce prototypes tailored to specific needs.

Moreover, our repair services ensure that your hydraulic systems remain in optimal condition, extending their lifespan and ensuring peak performance. Whether you're seeking hydraulic motors, custom-designed components of a hydraulic system, or hydraulic hose assemblies, our workshop can provide unmatched quality and precision.

Our engineering facilities include:

  • A 2m between centres Colchester lathe with a turning capacity of up to 315 mm diameter solid bar in most materials. This allows us to produce a wide range of non-standard parts including but not limited to hydraulic cylinders.
  • Also available are manual milling, drilling, and tapping machines as well as a Hurco 4-axis CNC milling machine; however, output from this is usually devoted to our bespoke pump manufacturing cell producing aluminium and cast iron gear pumps.
  • In addition to the above machinery we have MIG welding facilities with options of standard wire and flux core welding. Our fabrication facilities also include a plasma cutter and horizontal band saw.
  • A lapping/surface polishing machine is also available for giving new life to valve plates, shoe plates, and cylinder blocks.
  • Fully equipped booth with extractor for the painting of cylinders, powerpacks, pumps, and other hydraulic components in a variety of colours. Using standard machinery enamel or two pack paint with standard or etched primer.

Testing facilities:

There are three main test rigs on site for the testing of most hydraulic pumps and motors (motors are run-in and initially tested as pumps, although we do have the facility to test small-medium motors as motors). All test rigs record speed, flow, and pressure and electronically log the results; most sections also have temperature logging. Capacities of our test rigs are listed below:

Rig 1:

  • 45 kW
  • 0-1500 RPM
  • 3 sections; therefore we can run pumps with up to three outputs, soon to be upgraded to four
  • 300 bar max pressure
  • Electronically data logged at specified sample rate (our operational standard is 100 ms)
  • Suitable for gear, vane, and open loop hydraulic piston pumps on this rig

Rig 2:

  • 150 kW
  • 0-1500 RPM
  • 3 sections (again to be upgraded to 4)
  • 250 bar max pressure
  • Electronically data logged as above
  • Suitable for gear pump, vane pump, and open loop hydraulic piston pumps

Rig 3:

  • 110 kW
  • 0-2400 RPM
  • 4 sections for open loops tests
  • 2 closed loop systems (can test a tandem/double closed loop pump)
  • 300 bar max pressure
  • Electronically data logged as above
  • DC power source for solenoid controls etc (12 and 24 VDC)
  • Additional pilot source for closed loop units without boost pumps

And finally we have a test rig built specifically for the testing of scotch yoke pumps as found on the early Massey Ferguson tractors.

For a multiple section pump, all sections will be loaded sequentially so the max power will only relate to one section at a time (applies on all rigs in our hydraulic test facility).
