25 MPa • 3000 rpm • Counterclockwise rotation
CBHZ-F31.5-ALH6L is a forklift hydraulic gear pump offered by Ever Power Netherlands Branch. Nominal displacement is 31.5 ml/rev, the listed pressure is 25 MPa, and the speed reference is 3000 rpm.
Product overview & application
A forklift working pump supplies oil to lifting, tilting and, depending on machine layout, other hydraulic services. Displacement and pressure determine only part of the selection; rotation hand and mechanical interfaces often decide whether a replacement will fit.
This 31.5 ml/rev counterclockwise pump is one of the smaller displacement working-pump options in the forklift list, with 25 MPa and 3000 rpm listed.
Rotation hand
Most listed working pumps are counterclockwise; CBHZA-F36-AF is clockwise.
Duty rating
Compare system relief pressure and continuous demand with the selected model.
Mounting interface
Shaft, flange, drive features and ports must be checked against the original assembly.
Forklift hydraulic pump function
Check the drive-end suffix ALH6L and the actual flange and port positions. Hydraulic ratings do not provide enough information for a one-for-one fit claim.
Supply
The pump draws from the hydraulic reservoir through the suction circuit.
Work
Pressurised flow serves lift, tilt or another circuit as controlled by valves.
Return
The circuit returns oil to the tank; cleanliness and pressure relief protect the system.
Model range & comparison
Compare nearby pump references by actual hydraulic figures first. Connection geometry and pump drive arrangement still need to be matched independently.

Flow and pressure must be evaluated with the machine's pump drive, circuit relief setting and duty cycle. The listed maximum is not a blanket continuous-duty guarantee.
Interfaces, installation & maintenance
The 31.5 ml/rev displacement and 25 MPa rating belong to a counterclockwise working pump. Compare the pump with the installed drive-end geometry and machine hydraulic scheme. A near match in flow does not prove physical interchangeability.
A forklift enquiry is more precise when it includes the truck make and model, current pump code, shaft and flange photos, suction/discharge positions, relief setting and the required quantity.
Pump rotation
Check the rotation arrow and shaft-end viewing convention. Wrong-hand rotation can prevent proper suction and damage the pump.
Physical fit
Measure flange registers, mounting holes, shaft projection and inlet/outlet port centres against the removed assembly.
Hydraulic startup
Use the machine-approved hydraulic oil, maintain reservoir cleanliness and verify relief settings and operating noise after installation.
OEM cross-reference & replacement checks
Use the original pump marking for identification, then compare the shaft, flange, port layout, rotation and hydraulic duty. OEM reference numbers help start a cross-check; they do not by themselves establish one-to-one interchangeability.

Frequently asked questions
How do I identify clockwise versus counterclockwise?
Use the drive-end view and the machine or pump drawing to determine the rotation convention; never infer direction from the general forklift application alone.
Can a 24.5 MPa pump directly replace a 25 MPa pump?
Not automatically. Compare the duty rating, relief settings and thermal operating conditions as well as physical interfaces.
Can two 32 ml/rev pump models replace each other?
Matching displacement alone is insufficient. Shaft, flange, direction and port positions must also be checked.
What should be sent for a replacement quotation?
Include the forklift make/model, original pump reference, rotation, shaft/flange measurements or photos and the number of units needed.
Ordering, samples & delivery
Minimum order quantity (MOQ) is assessed by pump type, specification and total order value. Where production conditions allow, orders of just 1–2 units can be quoted, although the unit price will usually be higher than for a batch order.
Samples and small lots
New customers may request 1–5 samples when suitable. Availability and sample pricing are confirmed for the selected model.
Mixed-model orders
Different hydraulic pump models may be combined in one order; the target combined order value is approximately USD 1,500.
Production schedule
Standard parts: 10–25 working days. Customized assemblies: 20–45 working days. Project equipment: 45–120 working days.
Trade terms: EXW, FOB, CIF and DAP are normally available. FCA, CFR, CPT, CIP and DDP can be discussed according to the destination and shipment requirements. The agreed lead time and Incoterm will be stated in the formal quotation.
