Stainless Steel Diaphragm Pump, 0-50 m, Delivery Lift 70m

Stainless‑steel diaphragm pumps adopt stainless‑steel wetted parts, suitable for food‑grade, slight‑corrosive and hygienic working conditions. Both pneumatic‑driven and electric‑driven versions are available.

Diaphragm pumps separate process fluid from drive components via elastomer or PTFE diaphragms to achieve leak‑free conveying. Diaphragm material should be selected according to chemical compatibility of conveyed media.

👉 DBY Electric Stainless‑Steel Diaphragm Pump

Features
• Stainless‑steel wetted components for hygiene and mild‑corrosion resistance
• Good solid‑particle passing performance for slurry and particle‑containing media
• Self‑priming design, no pre‑filling water required before startup
• Multiple optional diaphragm materials to match different process media

Note: Pneumatic and electric stainless‑steel diaphragm pumps have obvious differences on suction lift, maximum head and dry‑running allowance. Do not confuse their operating limits. Always observe safety warnings on each dedicated product page.

Applications
Widely used in food & beverage, pharmaceutical, chemical, wastewater treatment for transferring hygienic liquid and mild‑corrosive slurry.

Important hints:
1. For flammable volatile media: electric DBY variant needs explosion‑proof motor; pneumatic QBY3 variant requires reliable grounding protection.
2. Allowable working temperature depends on diaphragm material. Check details on individual product page.
