Single Stage Double Suction Pump

YYO, YYOW series single stage double suction pump can be mainly suited for tap water plants, air conditioning water recycling, construction, irrigation, pump station, industrial water supply system, fire protection system, shipbuilding industries and so on.

Our single stage double suction pump features straight line type design, tight structure, attractive appearance, outstanding stability, long lifespan, low noise and convenient installation. For smooth operation, we optimize the double suction impeller to minimize the bearing axial force and provide superior hydraulic performance. After precision casting, both the inner surface of pump casing and the impeller surface are extremely smooth with remarkable cavitation resistance and high efficiency. In addition, it is alternative to choose mechanical seal or packing seal. During assembly, there is no need to adjust our product. According to the conditions of use on site, customers can also select vertical or horizontal installation.
