What is the DVP LC 41?
The LC 41 is part of DVP’s LC range — 40 m³/h, ultimate 0.1 mbar, selectable gas ballast. 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 is the DVP LC 41 used for?
DVP’s datasheet for the LC 41 does not list specific applications. Pumps in DVP’s LC 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 41 is the right choice.

Figures are taken from DVP’s published datasheet for the LC 41 (part number 9601078). 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 41 compare with the rest of the LC range?
The closest alternatives by pumping speed are the DVP LC 20 and DVP LC 40. 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 41 (this pump) | 40 m³/h (50 Hz) / 48 m³/h (60 Hz) · ultimate 0.1 mbar |
|---|---|
| DVP LC 20 | 20 m³/h (50 Hz) / 24 m³/h (60 Hz) · ultimate 2 mbar |
| DVP LC 40 | 40 m³/h (50 Hz) / 48 m³/h (60 Hz) · ultimate 0.1 mbar |

DVP LC 41 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 41 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 41 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 41 reach?
The LC 41 reaches an ultimate pressure of 0.1 mbar absolute, operating continuously across 400 to 0.1 mbar (abs), with a nominal pumping speed of 40 m³/h (50 Hz) / 48 m³/h (60 Hz).
What oil does the DVP LC 41 take?
The LC 41 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 41 single-stage or two-stage?
The LC 41 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 41 have?
The LC 41 is rated at 1.1 kW (single-phase) / 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 41 cost?
Girovac quotes the LC 41 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 41?
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 41, and stock genuine spares.
