The TMHS is TIGERFLOW’s multistage centrifugal pump line with threaded ports, in six series from the TMHS1 to the TMHS20: the series number sets the flow class, and the number after the dash is the stage count, so a TMHS8-4 has more head than a TMHS8-2 at the same flow. Every model runs on an IP55 (TEFC) motor with a carbon / silicon carbide / Viton mechanical seal; single-phase motors on the small TMHS1 models, 208-230/460V three phase on the rest.
Included: the TMHS pump and its IP55 (TEFC) motor as one unit, with NPT female threaded ports.
Motor protection required, ordered separately: wire the motor through a correctly set motor-protective breaker or starter, by qualified personnel.
Piping, isolation valves and check valve: sized to your installation and ordered separately.
Covered for 12 months from the date of purchase under TIGERFLOW’s published warranty terms.
