Cartridge Kits for V10 V20 SQP and VTM42 Vane Pumps
Cartridge kits for V10 V20 V2010 V2020 SQP and VTM42 vane pumps, assembled and matched for compact power units machine tools and vehicle steering circuits.
Product Overview
These are the small frame kits. They cover the compact V10 and V20 family, the low noise SQP family and the VTM42 steering pump. All three are frames where a cartridge change is the sensible repair, because the housing rarely fails and a complete pump costs several times what the wearing parts cost.
| V10 and V20 frames | V10 V20 V2010 V2020 |
|---|---|
| SQP frames | SQP1 SQP2 SQP3 SQP4 SQP21 SQP31 SQP32 SQP41 SQP42 SQP43 |
| Steering frame | VTM42 |
Key Benefits
- Turns a scrap pump back into a working one for a small fraction of the replacement price
- Quick to fit, often without removing the pump from the machine
- Covers three families from one supplier, so one order covers a mixed workshop
- Kits held in stock for the common displacements
Application Scenarios
- Tail lift and access platform power units
- Machine tool clamping and indexing circuits
- Bus and truck steering circuits using the VTM42 frame
- Small tank top power units in general engineering
Who It Is For
- General repair workshops handling mixed equipment
- Commercial vehicle service centres
- Machine tool service engineers
- Distributors carrying small frame stock
Problems It Solves
- A small pump has lost flow and a new unit is out of proportion to the machine value
- Steering has gone heavy on a vehicle that is otherwise in good condition
- The workshop handles several pump families and wants one parts supplier
- Local supply for these older frames has dried up
Technical Features
- Assembled and matched cartridges for each frame
- Ground rotor slots and profile ground cam rings
- Cartridge seals included in the kit
- Kits for single and double frames
- Individually boxed and labelled with the frame code
Specifications
Performance figures depend on the exact variant, so we confirm them against your model code rather than publishing a number that may not apply to your pump.
| Kit contents | Rotor, cam ring, vanes, plates and pins |
|---|---|
| Frames | V10 V20 V2010 V2020, SQP1 to SQP43, VTM42 |
| Seals | Cartridge seals included, shaft seal kit separate |
| Assembly | Supplied assembled and matched |
| Marking | Neutral or your own part number on request |
| Packing | Oiled and vacuum sealed in an individual box |
Materials
| Cylinder blocks | Case hardening steel with a sintered bronze running face, bonded and machined after sintering |
|---|---|
| Pistons and shoes | Case hardening steel with a bronze shoe face, swaged and hydrostatically balanced |
| Valve plates | Bearing steel or bronze faced steel depending on the frame, lapped to a mirror finish |
| Drive shafts | Alloy steel, carburised and hardened on the spline and bearing seats, ground on centres |
| Vanes and rotors | High speed tool steel and case hardening steel, hardened and ground on all working faces |
| Cam rings | Bearing quality alloy steel, through hardened then profile ground |
| Seals | Nitrile as standard, fluorocarbon or polyurethane on request for hot or fire resistant fluid duty |
Manufacturing Process
- Turning and millingBlanks are turned and milled from certified bar and forging stock on CNC machines.
- Heat treatmentCarburising, quenching, tempering or nitriding to the route the original part uses.
- GrindingBores, spline seats and running faces are ground after heat treatment so distortion is removed.
- Lapping and superfinishingValve plates, shoe faces and block faces are lapped so the pair seals under pressure.
- InspectionDimensions, hardness and surface finish are recorded against the drawing on a sampling plan.
- Assembly and testComplete pumps are built, run in and tested for efficiency, leakage and noise before packing.
Quality Control
- Incoming material certificates are checked against the grade called for on the drawing.
- Hardness is measured after heat treatment on every batch and recorded on the batch card.
- Critical bores and running faces are gauged against the drawing tolerance, not against a sample part.
- Mating parts are matched as a set so the block, shoes and valve plate run in together.
- Rebuilt pumps are bench tested for volumetric efficiency, external leakage and sound level.
- Parts are cleaned, oiled and vacuum sealed so they arrive without surface rust.
Certifications and Documentation
Supplied on request with an order. We do not claim approvals we cannot evidence.
| Material certificate | Mill certificate for the steel grade used in the batch |
|---|---|
| Hardness report | Surface and core hardness readings after heat treatment |
| Dimensional report | Measured values for the critical features named on the drawing |
| Test bench report | Flow, efficiency, leakage and sound readings for a rebuilt pump |
| Packing list and photographs | Carton contents and photographs of the packed goods before shipment |
Customization Options
- Shaft and splineKeyed, straight or splined shaft ends built to your sample or drawing.
- Port and mountingFlange, thread and mounting pattern matched to the pump already on the machine.
- Seal materialNitrile, fluorocarbon or polyurethane for hot oil, fire resistant fluid or low temperature duty.
- Rotation and displacementLeft or right hand rotation and the displacement code your circuit was set up for.
- Marking and packingNeutral packing, your own carton artwork and your own part number laser marked on the part.
Comparison With Other Products
| Point | V10 and V20 Kits | SQP Kits | VTM42 Kits |
|---|---|---|---|
| Typical machine | Tail lift and compact power unit | Machine tool and tank top unit | Bus and truck steering |
| Priority | Lowest repair cost | Low noise after repair | Continuous duty life |
| Sections | Single and double | Single and double | Single |
| Fitted on machine | Usually yes | Usually yes | Pump normally removed |
Use Guide
- Identify the frame and displacement from the model code before ordering.
- Open the pump on a clean bench and keep the cover bolts in order.
- Check the housing bore and cover face for scoring.
- Fit the cartridge to suit the rotation, then renew the shaft seal.
- Refill, bleed and run at low pressure before applying working load.

Frequently Asked Questions
Can you supply all three families in one shipment?
Yes. Mixed orders are normal and everything ships together on one packing list.
Do the kits come with fitting instructions?
A short fitting sheet is included and the full installation guide is on the download page.
Are the kits interchangeable between families?
No. Each family has its own cartridge geometry.
How are they packed for stock?
Oiled, vacuum sealed and boxed individually with the frame code on the label.
Can we buy a trial quantity first?
Yes. Most distributors start with a small mixed order and then place a stocking order.
