ZTS Series Single-Stage Double-Suction Split Case Centrifugal Pump

ZTS split-case centrifugal pumps offer easy maintenance, interchangeable inlet/outlet, and versatile mechanical or packing seals for municipal, industrial, and agricultural water systems.

Product Features:

When operating normally, the pump can continuously convey liquids up to 80°C, and even up to 120°C for short periods.

Design and Technology

Double suction impeller, double volute structure, small radial force, higher efficiency; Center-split pump casing, maintenance does not require disassembling piping; Thickened rigid shaft, low vibration, long life; Rotor can be reversed for a short time, safe and reliable; Inlet and outlet can be swapped left and right, flexible installation; Mechanical seal/soft packing seal, no leakage.
