Aftermarket BMB Electric Grease Pump
This page describes an aftermarket electric grease pump that cross-references the Bijur Delimon BMB. Bijur Delimon is a trademark of its respective owner. This is an aftermarket pump, not manufactured, sponsored, or endorsed by Bijur Delimon. BMB designations are for cross-reference identification only.
The pump is a standalone integrated package combining a pump head, geared AC motor, and reservoir. It is built for medium and large machinery where consistent grease delivery matters. The unit supports dual-line and progressive systems in centralized lubrication layouts.
How the Pump Works
A positive-displacement plunger mechanism is driven by an eccentric cam. The geared AC motor turns the cam, which sequentially moves the pistons. Multi-piston firing order dampens pulsation at the outlet, helping maintain steady downstream pressure. An adjustable relief valve covers a range from 0 to 450 bar, with the factory default set at 400 bar. This protects connected distribution hardware from over-pressurization.

System Compatibility
The pump is listed for dual-line and progressive lubrication systems. It is commonly selected for press lines, conveyors, machine tools, and packaging equipment that use either architecture. Single-line use should be confirmed against the system architecture before ordering. For more detail, see dual-line lubrication systems and progressive lubrication systems.
Reservoir and Motor Selection
Choose an 8 L reservoir for restricted space or low consumption. The 15 L reservoir fits intermediate duty where refill access is available. The 30 L reservoir is for long refill intervals on large multi-point systems. Match motor voltage and frequency to the plant supply before ordering. A 50 Hz supply commonly pairs with 220-240 or 380-415 V motors, while a 60 Hz supply pairs with 243-277 or 420-480 V motors.
What to Confirm Before Ordering
Confirm reservoir size, motor speed at 63 or 125 rpm, voltage, relief-valve setting, and whether control equipment such as a level switch or pressure gauge is included. See the grease pump range for related configurations. For a configuration check and quotation, contact the team.
Frequently Asked Questions
Is 400 bar the normal operating pressure?
The 400 bar value is the max working pressure. The relief valve is factory-set at 400 bar and should be matched to the weakest component.
Which reservoir size should I pick?
Select 8 L for small space, 15 L for intermediate use, or 30 L for long refill intervals. Match the reservoir to consumption and available mounting area.
Which voltage do I need?
Match the motor voltage and frequency to your plant supply. Confirm 50 or 60 Hz and the available phase voltage before ordering.
What is the difference between 63 and 125 rpm?
The 63 rpm motor delivers 34 ml/min. The 125 rpm motor delivers 67 ml/min for faster system fill and larger distribution networks.
Is NLGI 3 grease acceptable?
Yes, the pump handles grease to NLGI 3. Verify fluid temperature remains within -20 to +80 C for reliable flow.
Can it run a single-line system?
Single-line use should be confirmed against the system architecture first. The pump is listed for dual-line and progressive systems.
Does the pump include controls?
Level switch and pressure gauge inclusion varies by configuration. Confirm these items before ordering with your stated pump part number.
What systems does this pump serve?
It serves dual-line and progressive lubrication systems. It is not intended as a direct single-line drop-in replacement without review.
What maintenance approach is recommended?
Follow the machine lubrication schedule and inspect the relief valve periodically. Check reservoir level and motor condition during regular service intervals.
