DVP LC 12WR Water-Resistant Rotary Vane Vacuum Pump

The DVP LC 12WR is a single-stage, oil-lubricated rotary vane vacuum pump built for wet duty from DVP Vacuum Technology. It pumps 12 m³/h and reaches an ultimate pressure of 50 mbar absolute. Girovac supplies the LC 12WR in the UK, stocks genuine DVP spares and oil, and services DVP pumps in-house. Price on application.

DVP LC 12WR at a glance

What is the DVP LC 12WR?

The LC 12WR is part of DVP’s LC-WR water-resistant range — 12 m³/h water-resistant rotary vane pump for wet duty. Oil-sealed rotary vane pumps like this one are the workhorses of industrial vacuum: the oil seals the clearances, lubricates the vanes and carries away heat, which is what lets a single-stage rotary vane pump hold a steady working vacuum under continuous duty.

What does WR mean on a DVP pump?

The WR models share the LC body but add a device that separates water condensate from the oil and expels it once the pump stops. That is what lets them run in air streams carrying far more water vapour than a standard pump could tolerate — and it is also why their ultimate pressure is higher. Choose a WR pump for wet duty, not for deep vacuum.

Standard equipment on the DVP LC 12WR

• Oil check valve
• Exhaust mist eliminator
• Continuously operating oil recovery valve
• Gas ballast, permanently engaged

What is the DVP LC 12WR used for?

DVP’s datasheet for the LC 12WR does not list specific applications. Pumps in DVP’s LC-WR water-resistant range are used across vacuum packaging, handling and lifting, printing, laboratory and general industrial vacuum duties. If you tell us the process, volume and target pressure, we will confirm whether the LC 12WR is the right choice.

DVP LC 12WR technical specifications

Figures are taken from DVP’s published datasheet for the LC 12WR (part number 9690042). Noise is measured to UNI EN ISO 2151. Need the pumping speed at your actual working pressure rather than the nominal figure? Ask us for the curve.

How does the DVP LC 12WR compare with the rest of the LC range?

The closest alternatives by pumping speed are the DVP LC 25WR and DVP LC 40WR. If you are between sizes, size on the volume to be evacuated and the time you have to do it in, not on the nominal figure alone.

Accessories and spares for the DVP LC 12WR

We stock genuine DVP consumables — inlet filters, exhaust filters, vanes, oil and service kits. DVP part numbers above are from the LC 12WR datasheet; quote them when you enquire and we will match them exactly.

DVP LC 12WR supply, spares and servicing from Girovac

Established in 1983, with more than 40 years in the industrial vacuum sector, Girovac supplies, services and stocks spares for DVP vacuum pumps from our workshop in North Walsham, Norfolk. We can supply the LC 12WR new, source genuine DVP spares, and repair, service or recondition DVP pumps. If you are pumping water vapour, use the gas ballast — it is what stops vapour condensing in the oil.

Routine care is straightforward: keep the oil clean and topped up, change it on schedule, and keep the inlet filter clear. Most cases of a not reaching ultimate vacuum come down to tired oil or a leak rather than a worn pump. See our DVP vacuum pump service guide for the full routine.

We do not list prices online. Every LC 12WR is quoted to your application, duty cycle and phase requirement, including delivery to anywhere in the UK. Contact us for a quote on price, availability and technical advice.

Frequently asked questions

What vacuum does the DVP LC 12WR reach?

The LC 12WR reaches an ultimate pressure of 50 mbar absolute, operating continuously across 400 to 50 mbar (abs), with a nominal pumping speed of 12 m³/h (50 Hz) / 14 m³/h (60 Hz).

What oil does the DVP LC 12WR take?

The LC 12WR uses DVP SW40 rotary vane pump oil, with a charge of 0.30–0.40 dm³. Change it when it darkens or the achievable vacuum drops off. Girovac stocks genuine DVP oil.

Is the DVP LC 12WR single-stage or two-stage?

The LC 12WR is a single-stage, oil-lubricated (oil-sealed) rotary vane vacuum pump. Single-stage pumps of this type typically reach the 10⁻¹ mbar region; for deeper vacuum you would need a two-stage pump.

What motor does the DVP LC 12WR have?

The LC 12WR is rated at 0.45 kW (single-phase) / 0.37 kW (three-phase) at 50 Hz and weighs 17.5 kg (single-phase) / 15 kg (three-phase). Tell us whether you need single-phase or three-phase when you enquire.

How much does the DVP LC 12WR cost?

Girovac quotes the LC 12WR on application rather than listing a price, because cost depends on phase, accessories and delivery. Contact us and we will come back with a firm price and lead time.

Can Girovac service or repair a DVP LC 12WR?

Yes. Established in 1983, with more than 40 years in the industrial vacuum sector, Girovac supplies, services and stocks spares for DVP vacuum pumps from our workshop in North Walsham, Norfolk. We service, repair and recondition DVP pumps including the LC 12WR, and stock genuine spares.
