Oil Lubrication Pumps

Oil lubrication pumps divide by working principle, and that choice decides everything downstream — pipe sizing, point hardware, monitoring. This page groups the catalog the same way: trochoid internal-gear pumps for continuous circulation, electromagnetic piston pumps for single-line resistance feeding, automatic reservoir pumps from 1 kg to 6 L for machine-mounted supply, and hand pumps for top-up duty.

Every number quoted below comes from a product title: 1.2-6 L/min trochoid kits at 220/380V, DC-220S 6 L reservoirs, DCB-2 electromagnetic piston units, Y-6 and Y-8 hand pump classes. Where a unit is a Bijur Delimon design, the table says so; where it is a generic-duty pump, it says that too.

For oil-mist and air-oil systems rather than pump-and-line circulation, the related pages cover that hardware separately — the units here push liquid oil through lines to points.

Oil Lubrication Pump FAQ

Trochoid or gear pump — which one circulates machine oil?

The trochoid units are the circulation family here: BRB and BBZ internal-gear designs, quiet and compact, with the electric kit versions stated at 1.2-6 L/min on 220V or 380V. A trochoid pair — one rotor inside a shaped housing — moves a steady stream suitable for filter loops and bearing galleries. Piston pumps meter; trochoid pumps flow.

What does the 1 kg to 6 L reservoir ladder actually change?

Refill interval and mounting, not principle — the ladder from 1 kg and 2 L up to 4 L, 4 kg and 6 L is the same automatic supply at increasing autonomy. A 1 kg unit suits a single gearbox; a DC-220S-class 6 L unit feeds a multi-point machine for weeks. The VERSA III 2 L unit and the Bijur 4 kg unit bring their own controller and metering heritage to the same mid-range slot.

What is a DCB electromagnetic pump for?

Single-line resistance feeding. The DCB-2 is a solenoid-driven piston pump — each stroke pushes a metered slug of oil through one small-bore line to injector or metering units, with stroke rate setting total delivery. That makes it the right choice where points are far apart and each needs a measured dose, rather than circulation around a loop.

Do I still need a hand pump if the machine is automatic?

Most plants keep them anyway — for first fills, flushing, and low points the automatic system does not reach. The 0.5 L hand pump handles spot work, Y-6 and Y-8 classes cover bench duty, and the lever-action L-type moves more oil per stroke. None of them replaces the automatic system; they cover what it misses.

Can you match a pump to my machine list?

Yes — send the machine list with point counts and oil grade through the contact page, and the selection comes back as a bill of materials: pump, metering hardware, line sizes and monitoring. Pumps alone do not make a system; the sizing work is where the savings are.
