Product Overview:
APIS-type single-stage double-suction centrifugal pump is a new product developed by our company in accordance with the American Petroleum Institute standard API 610. It is widely used for the transportation of crude oil, refined oil or other liquid chemical products, etc.
This series of products in the design, production and testing, etc. mainly follow the bellowing latest version standards and specifications:
API610 “centrifugal pump for industrial usage in petroleum, petrochemical and natural gas”
GB/T3215 “general technical specifications of centrifugal pump in refinery and chemical industry petrochemical complex”
GB/T13006 “NPSH of centrifugal pump, mixed flow pump, axial flow pump”
GB/T13007“centrifugal pump efficiency”
GB/3216-2005“rotodynamic pumps-hydraulic performance acceptance tests-grades 1 and 2”
JB/T8097“pump vibration measurement and evaluation”
JB/T8098“pump noise measurement and evaluation”
GB/T5656“technical specification of centrifugal pump
The technical parameter of type APIS pump
Pump inlet and outlet diameter: 80-400m
Capacity Q: 22-3200m³/h
Head H: 7-216m
Technical advantage
APIS pump is in full compliance with API610 standards
1.1 The service life is designed for more than 20 years (not include in wearing parts). The continuous working life is designed for more than 3 years.
1.2 When changed bigger impeller diameter or used different impeller hydraulic model, the pump head will be risen for more than 5% under the rated operating conditions.
1.3 APIS pump can run continuously in the rated speed 105% at least. In the emergency conditions, it can run in a short time at security speed higher than driver speed.
1.4 APIS pump is designed with NPSH safe margin to ensure the damage caused by cavitation, fluid return and fluid separate flow in all pump flow.
1.5 The pump working flow area in the range of pump flow 70%-120% of the impeller’s best efficiency point. The rated flow point is the range of pump flow 80%-110% of the impeller’s best efficiency point.
Split case structure, maintenance advantage
Axial split case structure with middle section of coupling between the connection of pump and motor makes it convenient for maintenance and disassembly. No need to open the pump case when replacement of pump seals and bearings. No need to remove piping and motor when checking the pump parts inside.
Perfect monitoring systems for pump units
To protect the security and comprehensive monitoring equipment unit operation, our APID serial pump can be selected the following monitoring system according to the actual situation of the user: Bearing temperature monitoring system, vibration system, and leakage monitoring system.
