Circulating Water Vacuum Pumps
Circulating Water Vacuum Pump - Lab Vacuum Source
Water-circulating vacuum pumps are the economical vacuum source for rotary evaporators, filtration and general bench chemistry. No oil mist, reduced water consumption thanks to recirculation, and multiple taps let one pump serve several workstations simultaneously. PTFE valves and 1Cr18 stainless steel construction handle solvent-laden vapor streams.
Industries
Typical laboratory environments
- University labs

Catalog Highlights
What the product catalog adds
These points are drawn from the supplied LM product catalog and turned into buyer-facing detail.Circulating water vacuum pumps offer low noise, stable performance and an oil-free vacuum source.
PTFE anti-corrosive valves and 1Cr18 stainless wetted elements handle harsh chemical environments.
Novel water recycling design reduces water consumption while offering multiple vacuum taps.
Buying Guidance
How to specify the right system
Premium instrumentation decisions should account for methods, workflow and lifecycle service before the purchase order is issued.Sizing & throughput
For hard vacuum applications (molecular distillation, freeze drying) use a rotary vane oil pump instead.
Compliance & hazloc
Match pump tank capacity to throughput — larger evaporators need the 50L SHB-B95 model.
Power & utilities
Keep replacement PTFE valves on hand; they wear under aggressive solvents.

Buyer Notes
What usually matters during internal approval
These points help procurement and engineering move from browsing to approval without the usual back-and-forth.This is an economical oil-free vacuum solution suitable for routine bench extraction and filtration.
For deep high-vacuum applications (molecular distillation or freeze drying), we recommend sliding vane oil pumps instead.
