Therefore, the user will experience a trouble-free and cost-saving operation.

User advantages

No oil contamination

Simple and easy to clean on-site

No cooling water required

Extremely efficient air cooling, low heat emission

Corrosion-resistant pump chamber and stainless steel claws

Energy saving by operation with variable speed drive

Plug and go

Plug and go

  • Very easy to install: you connect it to electrical power, and it runs
  • No demand for expensive cooling water
  • Extremely efficient air cooling for lowest operation temperature
  • Variable speed-ready to improve the process and generate energy savings
  • We can offer our CLAWVAC pumps combined with a smart elctrical cabinet as a system: the CLAWVAC CPi B system
Harshest applications ready

Harshest Applications Ready

  • Built-in corriosion resistance
  • Completely cleanable
  • Segregated gearbox design avoids oil contamination of the process
  • Cooled and designed to guarantee the highest uptime
Extended uptime

Extended uptime

  • Wear free pump chamber
  • Durable and dependable components for extended lifetime
  • Long service intervals:
    • 20,000 hr between oil changes
    • Major overhauls extended to 48,000 hrs
Completely cleanable

Completely cleanable

  • The user has full and easy access to all media touched surfaces.
  • Housing and claws can be disassembled without need for resetting of the gear timing. 
  • The big-size silencer reduces the sound level a bit and allows condensate draining through the drain port.
High capability

High capability for demanding applications via:

  • Corrosion resistant stainless steel claws 
  • Resistance to high water vapor or water slugs
  • Coated and corrosion resistant pumping chamber
  • Drainable silencer
CLAWVAC CPi B System

CLAWVAC CPi B System can replace your big liquid ring vacuum pumps

Thanks to its unique design, CLAWVAC combined with the right Leybold accessories can replace a liquid ring vacuum pump in many processes. Switching to our dry technology, you will generate many improvements:

  • Huge cost savings: no water consumption, no water treatment anymore
  • Lower power consumption
  • Stable process performance, independent from water temperature
  • Better environment impact of your industrial plant, as water is becoming a valuable asset in many parts of the world.
