API Standard Petrochemical Self-Priming Pump (OH2)
This series of self-priming pumps includes horizontal internal mixing self-priming pumps, synchronous discharge-suction pumps, vertical seal-less self-controlled self-priming pumps, and high-performance intelligent self-priming pumps.
Description
This series of self-priming pumps includes horizontal internal mixing self-priming pumps, synchronous discharge-suction pumps, vertical seal-less self-controlled self-priming pumps, and high-performance intelligent self-priming pumps. Among these, the high-performance intelligent self-priming pump employs an intelligent vacuum extraction device for rapid air discharge and vacuum creation. The maximum suction depth reaches up to 8 meters, while other self-priming pumps achieve 5 to 6 meters. These pumps offer advantages such as easy installation and maintenance, and are primarily constructed from two material series: metal and non-metal.
Structure and Performance
The pump body features a radially split volute casing design with an optimized impeller, achieving a self-priming height of up to 9 meters. It delivers rapid priming, smooth operation, and low noise levels. The pump inlet is engineered as a high-pressure inlet, enabling adaptation to high-pressure delivery conditions and ensuring efficient performance under complex operating conditions.
Flow range: 0.8 to 400 m³/h; Head range: 16 to 250 m; Operating temperature: -80°C to 450°C; Operating pressure: Up to 5.0 MPa.
Use of materials
The primary materials are divided into two series: metallic and non-metallic.
