What is the DVP LC 41WR?
The LC 41WR is part of DVP’s LC-WR water-resistant range — 40 m³/h water-resistant rotary vane pump with IE3 motor. 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.
What is the DVP LC 41WR used for?
DVP’s datasheet for the LC 41WR 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 41WR is the right choice.

Figures are taken from DVP’s published datasheet for the LC 41WR (part number 9690043). 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 41WR 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.
| DVP LC 41WR (this pump) | 40 m³/h (50 Hz) / 48 m³/h (60 Hz) · ultimate 4 mbar |
|---|---|
| DVP LC 25WR | 25 m³/h (50 Hz) / 29 m³/h (60 Hz) · ultimate 4 mbar |
| DVP LC 40WR | 40 m³/h (50 Hz) / 48 m³/h (60 Hz) · ultimate 4 mbar |

DVP LC 41WR 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 41WR new, source genuine DVP spares, and repair, service or recondition DVP pumps.
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 41WR 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 41WR reach?
The LC 41WR reaches an ultimate pressure of 4 mbar absolute, operating continuously across 400 to 4 mbar (abs), with a nominal pumping speed of 40 m³/h (50 Hz) / 48 m³/h (60 Hz).
What oil does the DVP LC 41WR take?
The LC 41WR uses DVP SW60 rotary vane pump oil, with a charge of 1.5–2 dm³. Change it when it darkens or the achievable vacuum drops off. Girovac stocks genuine DVP oil.
Is the DVP LC 41WR single-stage or two-stage?
The LC 41WR 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 41WR have?
The LC 41WR is rated at 1.1 kW (three-phase, IE3) at 50 Hz and weighs 43 kg. Tell us whether you need single-phase or three-phase when you enquire.
How much does the DVP LC 41WR cost?
Girovac quotes the LC 41WR 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 41WR?
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 41WR, and stock genuine spares.
