Aftermarket JS Electric Grease Pump
This page describes an aftermarket electric grease pump that cross-references the Bijur Delimon JS series. Bijur Delimon is a trademark of its respective owner. This is an aftermarket pump, not manufactured, sponsored, or endorsed by Bijur Delimon. JS designations are for cross-reference identification only. The unit is a compact piston-driven pump for SLR and progressive grease systems on industrial machinery, machine tools, and light commercial equipment. Operation is controlled by a PLC or external controller, making the pump suitable for automated lubrication circuits where timed or counted grease delivery is required.
JS and JSP Variants
The JS variant is the pump unit only. It connects to an external progressive distributor or SLR control unit. This version is intended for systems where the distributor is already installed or mounted remotely. The JSP variant combines the pump with an integrated progressive distributor block, creating a compact all-in-one package. JSP suits new installations with up to about 8-12 points where a combined unit simplifies wiring and reduces the number of separate components. Both variants share the same pump core, reservoir options, and voltage range.

System Compatibility
The pump works in SLR and progressive architectures. The 25 ml/min figure is pump discharge, not the dose per point – the divider or meter units distribute it. For circuits built around a single supply line with metering devices, see single-line lubrication system. For circuits where a divider block feeds points in sequence, see progressive lubrication systems. The pump does not decide point dosage on its own; the downstream divider or meter sets the amount delivered at each lubrication point.
Part Number Structure
The part number encodes series (JS or JSP), reservoir size, voltage, and controller option. Order by full part number, not by model name. The same model name covers several voltages and reservoirs, so a generic request for a JS pump is not enough to select the correct unit. Always specify the complete code from the nameplate or system drawing. If the existing part number is not readable, confirm each field before ordering.
What to Confirm Before Ordering
Confirm JS or JSP. Confirm voltage: 12V, 24V DC, 220V, or 380V AC. Confirm reservoir size. Confirm grease grade NLGI 000-1; NLGI 2 needs written confirmation because it is not standard. Confirm low-level switch inclusion, since some reservoirs are fitted with a switch and some are not. For a broader view of pump formats, see grease pump. If the application details are not yet fixed, contact the team with the system layout before placing an order.
Frequently Asked Questions
What is the difference between JS and JSP?
JS is pump only, connecting to an external distributor or SLR control unit. JSP includes an integrated progressive distributor block for an all-in-one package.
Does this pump include a controller?
No, the pump requires an external PLC or controller, which is not included. You must provide a timed or counted control signal to run it.
Can this pump handle NLGI 2 grease?
No, the standard grease range is NLGI 000 to 1. NLGI 2 requires written confirmation before ordering because it is outside the standard range.
What does 25 ml/min mean for my system?
It is the pump discharge, not the dose delivered per lubrication point. The external divider or metering units distribute that total flow.
Which reservoir size should I choose?
Reservoir options are 0.5 to 2 L. Choose by refill interval and number of points served in the circuit.
What voltage options are available?
The pump is available in 12 or 24 VDC, plus 220 or 380 VAC. Confirm your control cabinet voltage before ordering.
What pressure does the pump produce?
Rated working pressure is 100 bar, which is 10 MPa or 1,450 psi. The integrated relief valve protects the circuit.
Can the JS pump feed an external divider block?
Yes, that is the JS configuration. The pump connects directly to an external progressive distributor or SLR control unit.
Can this pump be used in low-temperature service?
Yes, but low-temperature grease is needed for operation below -10 C. The pump body itself is rated down to -20 C.
Who builds this pump, and how do I get a quotation?
IsoHiTech Lubrication Systems, founded in 2023, engineering since 2006, builds and supports every unit. Email inquiry@isohitech.com for specifications and a quotation.
