What the VERSA III 4 L Pump Is
The VERSA III is a Bijur Delimon electric gear-type oil pump family for a single-line lubrication system. This page covers the 4 L reservoir member, often listed as a machine-side unit in a central lubrication system. An electric pump with a small reservoir suits oil feed to bearings and guideways; a controller cycles the pump and injectors meter the oil.
Published Listing Values
The published listing values for this 4 L member are output 210 ml/min and maximum pressure 2.5 MPa, which equals 25 bar. These figures come from distributor catalog listings rather than a current official datasheet. The official Bijur Delimon line today centers on other pump families, so treat every listing value as listed and verify against the nameplate.
The 4 kg Figure Decoded
Listings describe this unit as “4 kg”. That 4 kg figure is the reservoir oil capacity, about 4 L of oil, not the dry mass of the pump. Buyers comparing shipping weights must not read it as pump weight.
The VERSA III Family: 2 L Versus 4 L
The 2 L sibling is covered on the linked 2 L VERSA III oil pump page. That 2 L member lists 125 ml/min at 50 Hz, 110/220 VAC, 20 bar maximum pressure, and a 16 bar relief setting. This 4 L member lists a higher output of 210 ml/min and a higher maximum pressure of 2.5 MPa, which is 25 bar.
Voltage and Suffix Verification
Voltage is not confirmed in the listing for this 4 L member. Nameplates in this family appear as 24 VDC or 110/220 VAC depending on configuration. Read the motor nameplate before ordering a replacement. Related references 53618, 53618-1, and 52686-1 appear in listings, but the functional differences between these suffix variants are not established in public documentation. Confirm the exact suffix from the nameplate during quotation.
Replacement Checklist
Before selecting a replacement, verify the reservoir size, listed output, maximum pressure, motor voltage, and exact suffix reference.
- Confirm the reservoir is the 4 L version, not the 2 L sibling.
- Check the motor nameplate for 24 VDC or 110/220 VAC.
- Match the listed output of 210 ml/min and maximum pressure of 2.5 MPa.
- Record the reference 53618, 53618-1, or 52686-1 exactly from the nameplate.
- Treat all values as listed, not official, and verify against the unit.

Frequently Asked Questions
Is the 4 kg figure a dry mass?
No, the 4 kg figure is the reservoir oil capacity, about 4 L of oil. It is not the dry mass of the pump.
What listed output does this 4 L member provide?
The listed output is 210 ml/min for this 4 L reservoir member. Distributor catalog listings show this value, not an official datasheet.
What is the maximum pressure in bar for this unit?
The maximum pressure is 2.5 MPa, which equals 25 bar. This is a listing value, so verify it against the pump nameplate.
Which voltage does the motor use?
The listing does not confirm the voltage for this 4 L member. Nameplates may show 24 VDC or 110/220 VAC depending on configuration.
How does the 4 L model compare with the 2 L sibling?
The 2 L sibling lists 125 ml/min at 50 Hz and 20 bar maximum pressure. This 4 L member lists 210 ml/min and 2.5 MPa, or 25 bar.
What do suffix references 53618 and 52686 indicate?
The exact functional differences between 53618, 53618-1, and 52686-1 are not established in public documentation. Confirm the suffix from the nameplate before quotation.
Is this pump covered by a current official datasheet?
These listing values come from distributor catalog listings, not a current official datasheet. The official Bijur Delimon line today centers on other pump families.
Can this pump feed machine bearings and guideways?
Yes, an electric pump with a small reservoir suits machine-side single-line oil systems feeding bearings and guideways. A controller cycles the pump and injectors meter the oil.
Why should I read the motor nameplate first?
Voltage and suffix are not fixed for every VERSA III configuration. The nameplate is the only reliable source before you order a replacement.
