■Conforms to API610 10thAPI 11th standard,with high reliability and long life.

■Shaft diameter enlarged, shafting stability coefficient (L3/D4) 9.3~83;Small flexibility of mechanical seal,axial movement of shaft is less than 0.05mm.

■Impeller is precisely casted,which dynamic balance up to G2.5; High universalization and standardization. Pump casing is non-interchangeable because of different pressure,other parts are all interchangeable.

■Shaft sealing conforms to API682 2th edition standard.

■Patent product non-contact and non-sparking oil sealing,which prevents the entry of water into the oil reservoir.

■Monitor system can be configurated,which including the monitoring of pump vibration,bearing temperature rising,pressure at the pump inlet and outlet,flow rate,loading at the driving end.

■Single stage,cantilever type petrochemical process pump,horizontal center line mounted. Dual volute casing design for pump outlet diameter above 80 mm.

■Cooling jacket and steam jacket is available.

■Space of sealing chamber conforms to the requirements of API682 standard,there’s enough room for tandem type and double mechanical seal.

■Based on different application,the bearing housing can be configurated with water cooling,air cooling or heater.

■Back pull design,the rotary part can be removed out from casing without dismantle the pipelines.
