CSG Series Marine Vertical Centrifugal Pump

CSG Series Marine Vertical Centrifugal Pump

Introduction

CSG type water pump using IS type centrifugal pump performance parameter, coaxial pump machine has the advantages of simple structure, in strict accordance with international standards of ISO2858and the new national standards for the design of successful energy efficient products is to replace IS type horizontal pump, type DL pump and conventional products centrifugal pump. Basic type, expanding type, A, B, C cutting type and so on more than 400 kinds of specifications. According to the flow medium and temperature difference, the design and manufacture of same parameters of pump hot water (200℃), chemical pumps, oil pumps, explosion-proof chemical pump.
