Elmo Rietschle VC303 / VC 300 Overview
The VC range is widely associated with deep-vacuum industrial service, combining high pumping speeds with a stated 0.1 mbar ultimate pressure.
Oil inside the pump lubricates the moving components, contributes to sealing between the vanes and pump body and assists heat control during operation. Correct oil condition and effective exhaust separation are therefore important to long-term performance.
The three-phase motor rating is 5.5 / 7.5 kW at 50Hz / 60Hz. Motor voltage and exact build configuration should always be confirmed from the existing pump nameplate.
Vacuum Pumps UK can assess replacement requirements, while VacAir Superstore can support existing pumps with parts, oil separators, oil, servicing and workshop repair.

› plastics and composite processing
› printing and paper machinery
› vacuum lifting and handling
Actual suitability depends on the required working vacuum, process gas, contamination level and duty cycle. Applications involving significant vapour or aggressive process gases should be reviewed before selecting a standard oil-lubricated pump.
DVP LC305
Oil lubricated rotary vane vacuum pump
Comparable DVP Alternative
Consider the DVP LC305
Where an exact Elmo Rietschle replacement is not essential, Vacuum Pumps UK can assess the DVP LC305 as a closely matched alternative for the application.
The DVP LC305 provides a nominal capacity of 305 / 365 m³/h at 50Hz / 60Hz, compared with 300 / 360 m³/h for the Elmo Rietschle VC303 / VC300.
Both pumps have a stated ultimate pressure of 0.1 mbar absolute.
Final suitability should be checked against the machine duty, mounting dimensions, inlet position, connection size, motor voltage and the actual pressure at which the pump operates.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Elmo Rietschle VC303 / VC300 Replacement Comparison
The principal figures below provide a quick comparison. They do not replace an application check because pumping speed at the actual working pressure can be more important than nominal free-air capacity.
| Specification | VC303 / VC300 | DVP LC305 |
| Nominal Capacity 50Hz | 300 m³/h | 305 m³/h |
| Nominal Capacity 60Hz | 360 m³/h | 365 m³/h |
| Ultimate Vacuum | 0.1 mbar abs. | 0.1 mbar abs. |
| Motor Power 50Hz | 5.5 kW | 7.5 kW |
| Motor Power 60Hz | 7.5 kW | 8.6 kW |
Elmo Rietschle VC303 / VC300 Parts, Oil Separators, Oil, Service and Repair
Many Elmo Rietschle oil lubricated pumps remain in service for long periods, so maintaining the existing unit can be a very practical option. Our sister company VacAir Superstore specialises in consumable service parts and workshop support for Elmo Rietschle vacuum pumps.
VacAir can assist with routine maintenance, reduced vacuum, exhaust smoke or oil mist, oil leaks, overheating, unusual noise and more extensive internal pump damage.
Spare Parts
Replacement service and repair components including gaskets, seals, couplings, valves, filters and internal mechanical parts where required.
Oil Separators
Correct exhaust separators are essential for controlling oil mist, maintaining exhaust back pressure and returning separated oil to the pump.
Vacuum Pump Oil
Correct oil grade and regular oil changes help protect internal components, maintain sealing and preserve vacuum performance.
Service & Maintenance
Planned servicing can include oil and filter changes, separator replacement, inspection, vacuum testing and investigation of performance loss.
Repair & Overhaul
Where routine servicing is not sufficient, workshop strip-down, dimensional inspection, repair, rebuild and performance testing may restore the pump for continued service.
