24V Grease Pumps

24V DC is the system voltage of trucks, buses, construction machines, and heavy agricultural equipment — so a 24V grease pump can draw power straight from the machine it lubricates. That makes this class the working core of on-vehicle centralized greasing: pump, metering, and lines installed once, then feeding bearings on a timer.

IsoHiTech catalogs fourteen models on this page: progressive and SLR system pumps, dual-voltage 12/24V units, high-pressure Bijur Delimon models, and a few bucket, drum, and cordless units that also run on the 24V platform — each cross-listed where it fits another category.

Choosing a 24V Pump

Decide by what the pump has to drive — a full divider-block circuit, an SLR line, or just flexible points:

Duty on the machine	Type	Cataloged as
Progressive circuit, many points	Progressive pump	SK-505BM 14.7 MPa; DC24V-B 1-3 outlets; DZGK dual-voltage; CSK units
Single-line resistance (SLR) feed	SLR / dual-mode	Bijur Delimon DS, 15 MPa, 25 ml/min; IS, 16-25 MPa
Wet, washed-down machines	Protected housing	24V DC automatic pump, IP69K, NLGI #000-#2
Cartridge lube on the vehicle	Cartridge pump	Bijur Delimon FS, 120 bar
Replacing a discontinued OEM pump	Direct replacement	P203 replacement, SKF Lincoln compatible

24V Grease Pump FAQ

Why 24V rather than 12V for machine-mounted pumps?

Because the machine supplies 24V. Trucks, excavators, and heavy ag equipment run 24V electrics, and tapping that bus avoids a voltage converter. The dual-voltage DZGK, CSK, and SK-505BM units accept both, so the same pump fits mixed fleets — they are also cataloged under 12V grease pumps.

What is the difference between progressive and SLR here?

A progressive pump pushes grease through divider blocks: every point gets its share, and a blocked point stops the whole cycle — which is also how you detect a failed feeder. SLR (single-line resistance) meters each point through its own injector at lower flow; the DS (25 ml/min) covers both modes, which suits machines with mixed bearing sizes.

What grease grades can a 24V pump move?

Standard units handle NLGI 0-2. The IP69K automatic pump on this page is rated for NLGI #000-#2, so it also feeds semi-fluid greases used in sealed gearcases and wet underbody applications.

Does an IP69K rating matter on a greasing pump?

On construction and ag machinery, yes — it means the pump survives pressure washing and road grime, which is the main failure mode for vehicle-mounted units. Shop-mounted pumps do not need it, which is why the cheaper indoor models stay in the catalog.

Can IsoHiTech supply the pump with blocks and lines as a set?

Yes. Send the machine model, point count, and grease grade through the contact page, and the team will spec pump, divider blocks or injectors, tubing, and fittings as one matched set.
