Chemical Dry Pumps - Heavy Duty EDP Series
The Edwards EDP Series features a patented, non‑contacting reverse claw mechanism that delivers a completely oil‑free vacuum, eliminating the risk of process contamination. Engineered for demanding environments, these pumps offer exceptional tolerance to liquids and particulates in the gas stream and can operate seamlessly from atmospheric pressure down to their ultimate pressure.
An indirect cooling system further enhances safety and reliability by reducing the likelihood of chemical reactions within the pump. The EDP Series is the ideal choice for handling corrosive or harsh chemical vapors in heavy‑duty applications.
Available Capacities:
80 m³/hr · 160 m³/hr · 250 m³/hr · 400 m³/hr
Medium Duty EDS Series
The EDS Series is engineered to deliver exceptional performance in a compact footprint. High pumping speeds provide increased throughput when needed, while superior roughing capabilities ensure rapid pump down times and maximize operational uptime.
Featuring true plug‑and‑play convenience and tapered variable‑pitch dry screws, the EDS Series sets a new benchmark in dry screw pump technology. Its robust design offers a high tolerance for particulates, making it a reliable solution for demanding chemical processes.
Certified for use in hazardous environments and compliant with global explosion‑protection standards, the EDS range offers both safety and flexibility across a wide range of applications. It is ideally suited for medium‑duty processes with pH levels above 3.
Available Capacities:
200 m³/hr · 300 m³/hr · 450 m³/hr
Light Duty CDS Series
The Stokes CDS dry screw chemical vacuum pump is engineered for reliability in fine chemical and pharmaceutical applications. Its variable‑pitch dry screw mechanism provides excellent adaptability across a broad range of chemical processes. Designed for simplicity, the CDS Series offers true “plug‑and‑play” operation with minimal installation requirements, while still allowing configuration options for specialized process needs.
This series is well‑suited for solvent recovery and distillation processes with boiling points up to 120°C.
Available Capacities:
250 m³/hr · 400 m³/hr · 650 m³/hr · 800 m³/hr · 1300 m³/hr · 1600 m³/hr
