We are excited to present our ‘New Generation’ of Dynavac VCX Claw Pumps for oil-free vacuum and air/ gas compressor applications. Our manufacturing team has completely re-designed the VCX range resulting in extended longevity and significantly reduced noise levels. Maintenance has been even further reduced. The previous energy saving operating efficiency continues to be of significant benefit to our customers.
The latest range comprises 8 models, ranging from 60 to 1000 m3/ h. Vacuum is achievable down to -95 kPa (g) and delivery pressure of up to 2.2 bar.
Featuring, dry running pump chamber, long life, minimal maintenance, contamination-free pumped gas media and low cost of ownership
The latest VCX Series Range comprises an oil-free [dry] and contact-less pumping chamber, with 2 rotors driven by a remote gearbox. The pumping chamber requires no lubrication and its rotors are non-wearing. The gas being pumped is discharged from the pump chamber uncontaminated by lubricating oil. The need to trap and filter oil from the discharge is completely eliminated along with related servicing. In cases of pond aeration and breathing apparatus, the pristine gas leaving the VCX Claw pump is ready for use with no additional treatment or filtering required. All shaft bearings and gears are now oil-flooded, eliminating the need for a routine greasing schedule.
The latest VCX Claw Pumps are compactly configured with two integrated silencers, minimizing noise and site footprint. To save further energy, the latest VCX Claw pumps were designed for use with optional Variable Speed Drives, enabling customer to choose to operate at the most efficient speed for the application, or at up to 60Hz speed if higher speeds are required.
New, easy to remove Claws
For routine inspection and cleaning, all our new models now feature easily removed claws. The stator/end cover is easily removed, without having to release out-rigger bearings or timing gears.
Larger range up to 1000 m3/h
The latest VCX range offers 8 standard models with pumping speeds of 60, 100, 150, 250, 300, 400, 500 and 1000 m3/h
Reduced maintenance means lower operating costs
Apart from routine visual and audible checking, maintenance is almost a thing of the past. Replacement of gearbox oil, is the only service requirement on the latest VCX range. Oil changes are only necessary every 20,000 running hours. Furthermore our largest model requires only 2 litres of oil.
Special features and benefits
For two decades now, Dynavac has been a leader in dry claw vacuum pump and compressor technologies. We have built a great reputation in supplying our customers with reliable solutions, assuring them confidence and peace of mind. The technological developments and the successful release of the new VCX Claw Pumps range add to our already strong product list and industry capabilities.
Position of the Gear, Rotor and Silencer

Features
|
Benefits
|
|
Greater design efficiency
|
15% saving on power costs
|
|
Dry Running - Oil Free
|
Discharge air/gas leaving the pump is free of polluting oil vapour. Gas is not contaminated (see note 1)
|
|
Lower maintenance costs (see note 2)
|
Less than 2 litres of oil required. Gearbox Oil change required every 2 years only. (see note 3)
|
|
Claws (Rotors) are contact free
|
No friction or wear in the pumping chamber
|
|
Claws can be removed easily (i.e. for cleaning if needed) with no need to retime of the gears
|
Maintenance easier and faster thus reducing downtimes and costs.
|
|
Horizontally configured gearbox
|
Improved lubrication to gears and bearings
|
|
All bearings now oil lubricated from gearbox oil reservoir
|
No greasing of bearings required
|
|
Direct driven
|
No belt drive maintenance required
|
|
Air Cooled
|
No water cooling required
|
|
Pump chamber configured to self-drain
|
Residual moisture in chamber drains when pump switched off. Avoids chamber corrosion.
|
|
Reduced exhaust noise
|
Now equal to oil sealed rotary vane pumps
|
|
Low life cycle costs
|
Long life construction, Low maintenance and low operating costs
|
|
Environmentally friendly
|
Reduced carbon footprint
|
|
Easy to operate
|
Reduced operating costs
|
|
Can operate between 20Hz and 60Hz with VSD
|
Performance can be tuned to meet end users duty requirements as well as reducing energy consumption
|
|
Notes:
- Oil sealed pumps require constant monitoring of exhaust filters and replacement generally once per year.
- On ‘cost of ownership’ basis, additional purchase price of claw pumps is paid back after the
- First year, and annual savings continue for the life of the pump.Oil sealed pumps need 6 monthly oil changes [5-15 litres depending on model]
