Elmo Rietschle VCAH250 Vacuum Pump
The Elmo Rietschle VCAH250 is a high-capacity oil flooded rotary vane vacuum pump with a nominal pumping speed of 250 / 300 m³/h at 50Hz / 60Hz.
With a stated ultimate pressure of 0.5 mbar absolute, it combines the highest capacity in the VCAH100–250 group with the deeper vacuum performance associated with the VCAH versions.

Elmo Rietschle VCAH250 Overview
The VCAH250 is the largest of the VCAH100, VCAH160 and VCAH250 models. Elmo Rietschle’s operating information identifies the VCAH range for industrial vacuum service and gives the VCAH250 a nominal capacity of 250 m³/h at 50Hz with an ultimate vacuum of 0.5 mbar absolute.
At this capacity, replacement selection should consider the complete system. Pipework size, evacuation volume, operating pressure and whether the pump runs continuously or cycles with the machine can all influence the pumping speed actually required.
The pump uses oil for lubrication, sealing and heat control. Inlet filtration, correct oil condition and effective exhaust oil separation are therefore important to long-term performance.
The published three-phase motor rating in the supplied specification data is 5.50 / 7.50 kW at 50Hz / 60Hz. Motor voltage and the exact build of an existing pump should be confirmed from its nameplate.
Vacuum Pumps UK can assess replacement requirements, while VacAir Superstore can support an existing VCAH250 with parts, oil separators, oil, servicing and workshop repair.

Typical VCAH250 Applications
› larger vacuum packaging machinery
› vacuum forming and plastics processing
› central vacuum installations
› industrial process vacuum
› printing and converting equipment
› high-throughput production machinery
The VCAH250’s combination of 250 m³/h capacity and 0.5 mbar ultimate pressure makes it relevant where both relatively high air displacement and deeper vacuum are required.
Actual suitability depends on the required working vacuum, process gas, contamination level, evacuation volume and duty cycle. Applications involving aggressive or inflammable gases require appropriate special consideration rather than assuming a standard pump is suitable.
DVP LC305
Oil lubricated rotary vane vacuum pump
305 / 365 m³/h
Comparable DVP Alternative
Consider the DVP LC305
Where an exact Elmo Rietschle replacement is not essential, Vacuum Pumps UK can assess the DVP LC305. It should be regarded as a higher-capacity alternative rather than a like-for-like match: the LC305 provides 305 / 365 m³/h compared with 250 / 300 m³/h for the VCAH250.
The current DVP specification gives the LC305 a total final pressure of 0.1 mbar absolute, compared with 0.5 mbar for the VCAH250. The extra nominal capacity and different motor requirement mean the application and installation need to be checked rather than selecting on ultimate vacuum alone.
Final suitability should include pumping speed at the actual operating pressure, pipework, mounting dimensions, inlet and exhaust positions, connection sizes, electrical supply and process conditions.
Vacuum Pumps UK is the UK and Ireland Master Agent for DVP Vacuum Technology.
Elmo Rietschle VCAH250 Replacement Comparison
The principal figures below show why the LC305 is a model to assess rather than a direct equivalent. Nominal free-air capacity alone does not establish suitability.
| Specification | VCAH250 | DVP LC305 |
| Nominal Capacity 50Hz | 250 m³/h | 305 m³/h |
| Nominal Capacity 60Hz | 300 m³/h | 365 m³/h |
| Ultimate / Final Pressure | 0.5 mbar abs. | 0.1 mbar abs. |
| Motor Power 50Hz | 5.50 kW | 7.5 kW |
| Motor Power 60Hz | 7.50 kW | 8.6 kW |
Elmo Rietschle VCAH250 Parts, Oil Separators, Oil, Service and Repair
For an existing VCAH250, repair or overhaul may be commercially preferable to changing the installation where the pump remains mechanically recoverable. VacAir Superstore supports Elmo Rietschle oil lubricated pumps with consumables, service components and workshop repair.
VacAir can assist with reduced vacuum, oil mist, oil leaks, overheating, unusual noise, routine maintenance and more extensive internal pump damage.
Spare Parts

Oil Separators
Correct exhaust separation helps control oil mist and maintain oil recovery.
Vacuum Pump Oil
Correct oil grade and regular oil changes support lubrication, sealing and vacuum performance.
Service & Maintenance
Planned maintenance can include oil, filters, separators, inspection and vacuum testing.
Repair & Overhaul
Workshop strip-down and inspection can establish whether repair or overhaul is economically worthwhile.
Elmo Rietschle VCAH250 Frequently Asked Questions
What type of vacuum pump is the VCAH250?
The Elmo Rietschle VCAH250 is an oil flooded rotary vane vacuum pump intended for industrial vacuum duty.
What is the VCAH250 pumping capacity?
The stated nominal capacity is 250 m³/h at 50Hz and 300 m³/h at 60Hz.
What ultimate vacuum can the VCAH250 achieve?
The stated ultimate pressure is 0.5 mbar absolute.
What is the difference between VCAH250 and VCEH250?
The principal published distinction is vacuum level: the VCAH250 is rated to 0.5 mbar absolute, while the VCEH250 is rated to 10 mbar absolute. Both are in the 250 m³/h class at 50Hz.
Can a VCAH250 be serviced or overhauled?
Yes. Depending on internal condition, servicing or workshop overhaul may be a practical alternative to replacement. VacAir can also assist with oil separators, vacuum pump oil and spare parts.
What replacement pump should I consider?
Where an exact Elmo Rietschle replacement is not essential, Vacuum Pumps UK can assess the higher-capacity DVP LC305 against the required flow, operating pressure, motor and installation.
