Petrochemical process pump
ZH series petrochemical process pump is developed according to the producing requirements of petrochemical industry, and it is OH2 structure(centerline mounted) type which conforms to API610(ISO13709) standard. There are elaborately designs on the mounting, connection, cooling and mechanical seal... Monitor system can be configurated. It is suitable to pump clean fluids, fluids with particles, flammable, explosive and corrosive fluids.There are various materials available for our petrochemical process pump, cast iron, stainless steel SS304, SS316, SS316L, 904L, duplex stainless steel CD4MCu, 2205, 2507, Alloy 20, Hastelloy, Titanium, Monel, Nickel...
■Flow rate: Q=4~2500 （m³/h）
■Total head: H=3~300 (m)
■Pump diameter: 50~350mm
■Max. pressure: 7.5Mpa
■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.
