CLD series centrifugal pump uses single-stage vane wheel structure with added full leak-proof unit, which has better sand proof effect thus improves pump reliability and durability. Using lengthened coupling and open-back pump body, pump rotor assembly can be removed without removing pump system pipes and motor, so that maintenance and service can be done easily. It is suitable for ship fire control, ballast, drain, sanitation and high building water supply and pressurization.

CBL-G series pump is the new generation product of previous CBL series pump with 2-stage vane wheel, capable of making adjustment under the two operation conditions of large lift small flow rate and small lift large flow rate. Using patent technology of full leak proof, wear of centrifugal pump rotor sealing elements and serious centrifugal pump leak due to sand are better avoided. It features higher reliability and longer non-leak time, suitable for ship fire control, ballast, drain, sanitation, industrial building and etc.

W-BL series variable vortex pump is single-stage shaft overhung corrosion resistance pump with independent adjustment characteristics capable of on-line adjusting pump characteristic curve without vane change, rotation speed change, disassembling and shutdown; it also features reliable sealing and no leak because of the double sealing structure, capable of conveying corrosive liquid without solid particles with temperature of -40～80℃ and viscosity of more than 5°E. Its major applications are radar electronic cooling system, chemical engineering, hospital, electronics and etc.

V series diesel seawater cooling pump is mainly used for cooling marine diesel engines, which cools and drains main engine by pumping seawater. The pump is directly connected with main engine through gears and driven by main engine power. It features compact structure, small size, reliable connection, strong resistance to corrosion, long no-leak operation time and etc.

With the patent technology of full leak-proof, the product can normally operate under a sand condition. It features shaft type and compact structure, small size, light weight, easy for installation and adjustment, advanced performance and high reliability. It is used in fields of ship fire control, sanitation, cooling and etc.
