Design
ZA series are with radial split casing,among which ZA are OH1 types of API60 pumps, ZAE and ZAF are OH2 types of API610 pumps. High generalization degree, no difference of hydraulic parts and bearing parts; series of pump can be installed insulation jacket structure; high pump efficiency; Bigger corrosion allowance for casing and impeller; Shaft with shaft sleeve, totally isolated to the liquid, avoid corrosion of shaft, improves lifespan of the pumpset; Motor is with extended diaphragm coupling, easy and smart maintenance, without taking apart pipes and motor.

Casing
Sizes over 80mm, casings are double volute type to balance radial thrust to improve noise and extend life span of the bearing; SLZA pumps are supported by foot, SLZAE and SLZAF are central support type.

Flanges
Suction flange is horizontal, discharge flange is vertical, flange can bear more pipe load. According to client's requirements, flange standard can be GB, HG, DIN, ANSI, suction flange and discharge flange have the same pressure class.Cavitation performanceVanes extend to suction of impeller, at the same time size of casing enlarged, thus make the pumps have better cavitation performance. For special purpose, induction wheel can be equipped to improve the anti-cavitation performance.Bearing and lubricationBearing support is a wholly one, bearings are lubricated with oil bath, oil slinger can ensure enough lubrication, all these prevent somewhere temperature rise because of lower lubricating oil. According to specific work condition, bearing suspension can be non-cooling(with steel heat), water cooling (with water cooling jacket) and air cooling(with fan). Bearings are sealed by labyrinth dustproof disc.Shaft sealShaft seal can be packing seal and mechanical seal.Seal of pump and auxiliary flush plan will be in accordance with API682 to ensure safe and reliable seal in different work condition.
Optional Classic seal flush plan

PLAN 11	PLAN 21
Working fluid enters seal housing through pipe line from pipe discharge	Circulating liquid enters sealing housing cooled by heatexchanger at discharge of pump
The plan mainly for condensated water, normal temperature steam, diesel etc (Not for high temperature condition.	Circulating fluid enters seal housing after cooled by heater exchanger from pump discharge.
PLAN 32	PLAN 54
Flush from outside	Back to back double mechanical seal for outside flush resource
Flush fluid enters seal housing from outside, the plan mainly for liquid with solid or impurities. (Attention outside flush fluid affect the liquid pumped)

Product Advantage

CASING √
Foot support structure

IMPELLER √ Close impeller. Thrust force of CZ series pumps are balanced by back vanes or balance holes, rest by bearings.COVER √ Along with seal gland to make sealing housing,standard housing should be equipped with various kinds of seal types.SHAFT SEAL √ According to different purpose, seal can be mechanical seal and packing seal. Flush can be inner-flush, self-flush, flush from outside etc, to ensure good work condition and improve life time.SHAFT √ With shaft sleeve, prevent shaft from corrosion by liquid, to improve life time. Back pull-out design Back pull-out design and extended coupler, without taking apart discharge pipes even motor, the whole rotor can be pulled out, including impeller, bearings and shaft seals, easy maintenance.
