Olive Branch Hydraulics supplies SGP1 series hydraulic gear pumps for replacement and equipment projects. Send your complete pump model, OEM part number and installation dimensions to select the correct specification. This page brings together SGP1 and selected CBHZ, CBHZG, CBHZA and CBHZB references to help buyers identify an existing forklift pump.
Product photographs show multiple configurations. A family name or a similar appearance does not establish interchangeability. Confirm the exact shaft, mounting, oil ports, displacement and rotation before placing an order. Supplied specifications are agreed for the selected configuration.
The following values are Shimadzu catalogue reference displacements, in cm³/rev. They are not a test certificate for every replacement pump. Equivalent manufacturers may use different nominal values.
| Reference model | Catalogue displacement (cm³/rev) |
|---|---|
| SGP1-16 | 16.2 |
| SGP1-18 | 18.3 |
| SGP1-20 | 20.4 |
| SGP1-23 | 23.7 |
| SGP1-25 | 24.9 |
| SGP1-27 | 27.8 |
| SGP1-30 | 29.9 |
| SGP1-32 | 33.2 |
| SGP1-34 | 34.1 |
| SGP1-36 | 36.6 |
In the standard reference coding, A identifies an 82.55 mm mounting pilot; F indicates rear-cover side ports and D rear ports. H identifies horizontal two-bolt mounting. Standard shaft codes 1 and 5 identify 13-tooth and 10-tooth splines. L and R mean counterclockwise and clockwise when viewed from the shaft end. Special OEM suffixes require their own drawings.
Customers may search for an SGP1 gear pump using the domestic CBHZ family designation. The model lists below identify related catalogue entries, not universal substitutes. Keep the full suffix when requesting a CBHZ forklift hydraulic pump or CBHZA replacement gear pump.
| Family | Published model references |
|---|---|
| CBHZ | CBHZ-F25-ALH6; CBHZ-F30-ALΦ; CBHZ-F32-ALH6; CBHZ-F32-ALH6L; CBHZ-F31.5-AL; CBHZ-F31.5-ALH6L |
| CBHZG | CBHZG-F23-ALφ; CBHZG-F25-ALφ; CBHZG-F26.5-ALΦL; CBHZG-F30-ALΦ; CBHZG-F30-ALφL; CBHZG-F30-ALΦL-G00; CBHZG-F32-ALφ; CBHZG-F32-ALφL; CBHZG-F32-ALH6L; CBHZG-F34-ALΦ13L |
| CBHZB | CBHZB-F28.2-ATΦ; CBHZB-F32-ATΦ |
| CBHZA | CBHZA-F25-AFΦ; CBHZA-F25-AFΦ13; CBHZA-F30-AFΦL; CBHZA-F32-AFΦ13L; CBHZA-F36-AFΦ |
Some catalogues use Φ, φ or Ф; others omit the symbol in search listings, such as CBHZG-F34-AL13L. Preserve the original nameplate designation for technical matching. CBHZ-F23-AL**, CBHZ-F25-AL**, CBHZ-F28-AL**, CBHZ-F30-AL**, CBHZ-F32-AL** and CBHZ-F36-AL** are manufacturer family patterns: the asterisks represent configuration options, not complete ordering codes.
The following references are drawn from service manuals and parts-supplier catalogues. They support an identification enquiry; they do not certify that every pictured Olive Branch pump fits every listed forklift. References listed together by a supplier must still be checked against the vehicle serial number and installation drawing. Engine codes describe configurations, not a complete vehicle identity.

For an SGP1 forklift hydraulic pump quotation, provide a clear photograph of the original nameplate and the complete truck model and serial number. Include the engine code, pump position and OEM part number. Measure the mounting pilot diameter and bolt centres, spline tooth count, shaft diameter and exposed shaft length. Record the inlet and outlet thread or flange dimensions and their positions.
Specify displacement in cm³/rev, operating pressure and speed, and rotation viewed from the shaft end. A 10-spline pump and a 13-spline pump require different drive connections. A clockwise pump must not be assumed suitable for a counterclockwise installation. Front and rear pumps on the same forklift can have different displacement, rotation and connections.
They are different model families. Certain complete models are listed as alternatives in equipment documentation. Compare the exact suffix and dimensions; do not replace a pump using only the series name.
Yes. Send the part number together with the truck serial number, old-pump photographs and measurements. We will use these details to prepare a configuration-specific quotation.
No. The original reference catalogue lists 33.2 cm³/rev for SGP1-32, while replacement catalogues can use different nominal values. Use the selected pump drawing and agreed specification.
This page presents Olive Branch Hydraulics products. Other brand names, model codes and OEM numbers are identification and application references; they do not imply manufacture or endorsement by those brands.
Send a sample or dimensioned drawing, required displacement, rotation and operating conditions. Discuss the proposed replacement specification before confirming an order.
