Aftermarket CSK Electric Grease Pump
This page describes an aftermarket electric grease pump that cross-references the Bijur Delimon CSK. Bijur Delimon is a trademark of its respective owner. This is an aftermarket pump, not manufactured, sponsored, or endorsed by Bijur Delimon. CSK designations are for cross-reference identification only.
The compact 24V DC machine-mounted pump feeds progressive divider valves. A worm and worm-wheel drive with a reciprocating piston delivers grease under pressure. This design differs from single-line parallel PDI systems. With progressive dividers, a blockage stops the divider for fault indication.
How the Pump Works
An eccentric wheel converts rotary motion to pumping action. Grease moves from the reservoir to a progressive divider manifold. The manifold gives sequential metered distribution to each lubrication point. If one point blocks, the divider stops, giving visual or electronic fault indication. A built-in jumper-selectable timer controller manages discharge intervals. An optional illuminated push button allows manual priming before start-up.

Elements and Outlets
The pump supports 1 to 3 pumping elements. Each element can feed an independent progressive divider circuit. Combined output scales with the number of active elements installed. Confirm the element count from the old pump nameplate before ordering.
Control and Monitoring
Jumper-selectable discharge intervals allow adjustment for the application. Status indication gives local feedback on divider movement and fault events. A factory-set over-pressure relief valve protects the pump and downstream components. Learn more about progressive lubrication systems and what is a central lubrication system.
What to Confirm Before Ordering
Confirm the element count, reservoir size, outlet thread, and controller settings. Check whether the outlet is 1/4 NPT or M12 x 1.5. Review the general grease pump range if the machine architecture is uncertain. For a configuration check or quote, contact the team.
Frequently Asked Questions
What is the difference between PDI and progressive lubrication?
PDI systems feed points in parallel from a single source. CSK feeds progressive dividers sequentially, so blockage stops the divider.
How many pumping elements does this pump have?
The pump comes with 1, 2, or 3 elements. Confirm the original pump element count before you order.
What is the output per pumping element?
Each element delivers about 5.5 ml/min at rated voltage. Total output scales with the number of active elements.
Can this pump handle NLGI 2 grease?
Yes, it handles NLGI 000 to 2 grease. Match the grease consistency to the central lubrication system requirements.
What happens if one lubrication point blocks?
The progressive divider stops when a point blocks. This gives visual or electronic fault indication for quick action.
Is a controller included with the pump?
Yes, a built-in jumper-selectable timer controller is included. It manages discharge intervals without an external unit.
What is the standard reservoir size?
The standard reservoir size is 2 L. Confirm reservoir height if the mounting space is tight.
What outlet thread does this pump use?
Outlet is 1/4 NPT or M12 x 1.5. Confirm the old fitting before ordering to avoid rework.
Can this pump run a dual-line system?
Confirm the machine architecture first. This is a progressive pump, not a dual-line pump.
