PEEK Chemical Dosing Gear Pump
PEEK chemical gear pump adopts high‑performance PEEK material for all wetted parts.
It is specially developed for highly corrosive chemical fluids.
With compact structure and precisely machined gear set, it can realize fluid transfer and metering for fine chemical, pharmaceutical, new‑material and reagent‑dosing processes.
Features of PEEK chemical gear pump
1. Superior corrosion resistance: PEEK material resists acid, alkali and partial organic solvents. Prevent medium contamination caused by metal corrosion.
2. High‑precision performance: Precisely meshed PEEK gears deliver stable low‑pulsation flow. Variable‑frequency motor is optional for flow adjustment.
3. Multiple sealing solutions: Single / double mechanical seal optional for toxic, volatile or crystallizable chemicals, effectively reduce leakage risk.
4. Light weight & low friction: Low friction coefficient, low running noise, suitable for 24‑hour continuous production.
5. Flexible drive & connection: Standard / explosion‑proof motor available. Flange or threaded ports can be customized.
Application of PEEK chemical gear pump
Fine chemicals, pharmaceutical intermediates, new‑material synthesis, water treatment, resin processing, pilot‑scale laboratory equipment.

FAQ:
Q: What is the advantage of PEEK gear pump compared with stainless‑steel pump?
A: Better corrosion resistance for some strong acid & organic solvents, avoid medium contamination by metal ions.
Q: Can PEEK chemical gear pump realize negative pressure discharge?
A: Yes. The precisely‑processed gear pair with small clearance. It can transport corrosive media under vacuum or reactor negative‑pressure condition. Please run at proper speed and dry‑running is strictly forbidden.
Q: What is max temperature of PEEK gear pump? Can it handle strong‑oxidizing media?
A: Normal working temperature for PEEK is ≤60℃. It is NOT suitable for strong‑oxidizing media such as concentrated nitric acid.
Please check MSDS to confirm chemical compatibility before selection.
