What the ZM1002 Pump Is
The SKF ZM1002 is an electrically operated, self-priming multi-circuit gear pump. It moves mineral or synthetic oil in a circulating or single-line lubrication system.
The ZM1002 is a current SKF listing, not a discontinued number. It is an oil pump only; the ZM gear pump family is not designed for grease.
This site supplies a direct aftermarket replacement when the complete order code is confirmed. Use it inside a central lubrication system that requires ten metered oil outlets.
Official Specifications
Key published values include:
- 10 outlets, each metering 0.2 L/min. The arrangement is 5 x 0.2 L/min plus 5 x 0.2 L/min.
- Nominal combined delivery approaches 2 L/min, but SKF specifies the pump per outlet, not by total flow.
- Maximum back pressure is 20 bar.
- Operating viscosity is 20 to 1000 mm2/s, depending on variant.
- Flow figures are rated at about 1400 rpm for at least one configuration; rating basis depends on the specific variant.
- Motor is three-phase AC, 220-240 / 380-420 V, 50 Hz.
- ZM family motor power is 0.18 to 0.37 kW depending on version.
- Operating temperature is +10 to +40 C.
- Protection class is IP54.
Reading a Complete ZM1002 Order Code
The designation ZM1002 alone identifies the pump body and outlet configuration, not a reservoir package. Reservoir, level switch, and controls are defined by the complete order code.
Suffixes such as +1FV identify a pump unit with reservoir; +1GD2 and +1GD3 assemblies also exist. Read the full nameplate before ordering.
The suffix determines tank size, level switch type, and exact motor power, which this site confirms during quotation. A partial code does not define a complete pump unit.
The ZM Family and Model Differences
The ZM gear pump family includes ZM50, ZM100, ZM200, and larger or smaller variants. These models provide about 1, 2, 5, 8, 10, or 20 outlets.
Per-outlet flow across the ZM family spans about 0.015 to 0.45 L/min. Maximum pressure is 20 or 30 bar depending on model.
A ZM1002 is not automatically interchangeable with another ten-outlet pump. Check outlet count and per-outlet flow before substitution.
Per-Outlet Flow Versus Total Flow
SKF rates the ZM1002 per outlet, not as a total flow pump. Each of the 10 outlets delivers 0.2 L/min at the rated condition.
The nominal combined flow of about 2 L/min is a reference sum. A buyer must not select a pump by total flow alone because each outlet feeds a separate point.
In a single-line lubrication system, a per-outlet specification prevents one line from robbing another. Confirm that your application needs exactly 10 discrete 0.2 L/min oil streams.
Selection Checklist for a Replacement
Check these items before ordering:
- Confirm the full ZM1002 order code and nameplate suffix, including reservoir option and level switch type.
- Confirm motor voltage and frequency against your supply: 220-240 V or 380-420 V at 50 Hz.
- Confirm oil viscosity within 20 to 1000 mm2/s and maximum back pressure below 20 bar.
- Confirm that the required per-outlet flow is 0.2 L/min and not another ZM family value.
- For a system that needs air-driven oil delivery, review this site’s pneumatic piston pump alternative.

Frequently Asked Questions
What oil types work with the ZM1002?
The pump handles mineral or synthetic hydraulic and lubricating oils. It is not rated for grease.
What does the 10 outlet configuration mean?
The pump has 10 outlets, each metering 0.2 L/min. The arrangement is 5 x 0.2 L/min plus 5 x 0.2 L/min.
Is the ZM1002 a complete pump unit with reservoir?
No, ZM1002 alone identifies the pump and outlet configuration only. The reservoir, level switch, and controls come from the complete order code suffix.
What is the maximum back pressure?
The maximum back pressure is 20 bar. Do not exceed this value in any oil circuit.
What motor voltage does the ZM1002 use?
The motor is three-phase AC, 220-240 / 380-420 V at 50 Hz. Verify the actual winding from the nameplate because variants differ.
What oil viscosity range is allowed?
The operating viscosity depends on variant, typically 20 to 1000 mm2/s. Confirm your oil falls inside the specific order code limit.
Can the ZM1002 pump grease?
No, the ZM gear pump family is an oil-only design. Grease would damage the close clearance gear elements and reduce metering accuracy.
What is the difference between ZM1002 and other ZM models?
Other ZM models like ZM50, ZM100, and ZM200 may have 1, 2, 5, 8, 10, or 20 outlets. Per-outlet flow across the family spans about 0.015 to 0.45 L/min.
How do I confirm the exact motor power and reservoir size?
Read the full order code suffix and nameplate on your existing pump. This site verifies those values during quotation to match your replacement.
