Diaphragm Pump

Product Overview

Diaphragm pump is an innovative pump type increasingly adopted across industrialized nations worldwide, replacing certain centrifugal pumps and screw pumps in petrochemical, ceramic, metallurgical, electronics and textile industries.

Key Features

• Handles free-flowing liquids as well as hard-to-pump viscous media combining superior merits of multiple pump types
• No priming water required with maximum self-priming lift reaching over 7 meters
• Outstanding solids passing capability suitable for viscous fluid up to 10,000 cP and solid particles up to 10 mm
• Isolating diaphragm separates process fluid from drive components to achieve zero leakage
• Shaft-seal-free construction greatly extends service life
• Pneumatic diaphragm pumps operate with compressed air enabling safe operation in flammable and explosive hazardous areas
• Can run dry, be fully submerged in pumped media and require no oil lubrication
• Two series available: DBY electric (≤3 kgf/cm²) and QBY air-operated (>6 kgf/cm²)
• Breakthrough diaphragm material technology ensures reliable and durable operation
