ZD ZDG ZDF ZDY ZMD Self-Balancing Multistage Pump

Product Features

1.Symmetric impeller layout mostly eliminates axial thrust; residual thrust is borne by back-to-back angular contact ball bearings. Balancing disc is canceled to remove friction and bypass loss, raising pump efficiency by 5%–14% and avoiding breakdowns from failed balance components for longer service life.

2.Proprietary anti-abrasion seal integrates merits of packing and mechanical seal: particle-resistant and leak-free for long-term service in solids-containing medium.

3.In-house developed waterproof bearing housing design prevents liquid intrusion under running or standby status, prolonging bearing lifespan and cutting maintenance expense.

4.Stable low-noise operation, wide performance curve, easy installation & maintenance.

Main Application

Mine slurry drainage, hot water, petroleum liquid, corrosive & abrasive medium pressurization.
