ZX series self-priming pump
ZX series chemical self-priming pump is based on the relevant technical information from domestic and overseas by adsorption, digestion, improved from development of energy-saving pump. It has several characters which include a compact structure, easy operation, smooth operation, easy maintenance, high efficiency, long life, and have strong self-absorption capacity and so on.No need to install the pipe end of the valve, before work just to ensure that there is quantitative pump priming can be.So it simplifield the piping system, and improved the working conditions.
■Flow rate: Q= 8～80 （m³/h）
■Total head: H=10～80 (m)
■Pump speed: n=1450/2900rpm
■Design temperature: T=-20～90℃
■Fluid s.g.: γ≤1.3
■Pump diameter: 50～350mm
■Solids Handling Impeller
Two-vane, semi-open, solids handling impeller handles up to 3" (76 mm) diameter solids, depending on pump model. Pump out vanes on impeller shroud reduce foreign material buildup behind impeller and reduce pressure on seal and bearings for extended pump life.
■Exclusive Abrasion-Resistant Seal
Exclusive double-floating, self-aligning oil lubricated mechanical cartridge seal with stationary and rotating face of silicon carbide is specifically designed for abrasive industrial waste water service.
■Removable Cover Plate
Removable cover plate provides quick and easy access to pump interior without disconnecting piping. Clogs can be removed and pump returned to service in minutes. Impeller, seal, wear plate and flap valve can also be accessed through cover plate opening for inspection or service.
■Replaceable Wear plate
ZW Series pumps feature replaceable wear plates which fasten to the cover plate and can easily be removed for inspection or service. No expensive castings to replace.
■Removable Rotating Assembly
Removal of rotating assembly allows easy inspection of pump shaft or bearings without disturbing pump casing or piping. On most models, simply remove four bolts from the back of the pump and the rotating assembly slides out.
ZW Series Pumps are available as basic units for connection to customers' power source or may be flex-coupled or V-belt driven by an electric motor. Pumps may also be powered by gasoline or diesel engines. Electric motor driven pumps with "standby" engine power are also available.
