The TSURUMI 100B47.5 is a submersible sewage pump from Tsurumi's B series (officially classed as a sewage and wastewater pump with a channel impeller). It has a 100 mm discharge and a 7.5 kW 4-pole three-phase dry-type motor. Its gray cast-iron shrouded single-channel impeller passes solids up to 40 × 61 mm and is designed to minimize trouble from clogged solids and fibrous matter, making it suitable for sewage and wastewater containing solids (0–40 °C, pH 5–9).

Selection note: the 100B47.5 is a non-clog sewage and wastewater pump, not a slurry pump. It is not suitable for dense sand, slurry or desilting work; for that duty, choose one of Tsurumi's construction slurry pumps, such as the KRD611. The standard model is not seawater-resistant and is not rated for liquids above 40 °C; seawater-resistant and high-temperature (up to 80 °C) versions are special-order options.

Key features

Anti-clogging channel impeller: the impeller itself forms a channel, so solids and fibrous matter are less likely to clog inside the pump. This model uses a shrouded single-channel impeller (radial gap) with 40 × 61 mm solids passage.
Dual inside mechanical seals: silicon carbide (SiC) faces isolated in an oil chamber, away from the pumped liquid, which reduces the risk of failure from dry running and adhering matter.
Tsurumi Oil Lifter: keeps the seal faces lubricated and cooled even when the oil drops to one-third of its normal level, extending seal life.
Built-in circle thermal protector (CTP): directly cuts the motor circuit on overheating or overcurrent.
Anti-wicking cable entry: stops water creeping into the motor by capillary action if the cable sheath is damaged or the cable end is submerged, and limits condensation inside the motor housing.
Continuous-duty dry-type motor: 4-pole induction motor, insulation class F, IP68.
Guide rail fitting available (TOS100B47.5): the pump can be lifted out and lowered back along guide pipes, so maintenance does not require entering the sump.

Applications

Buildings and facilities: sewage and wastewater discharge from sumps and sewage pump rooms
Sewage and wastewater treatment: transfer of wastewater carrying solids and fibrous matter
Industrial sites: industrial wastewater drainage
Flood control: stormwater and floodwater drainage
Irrigation and recreation facilities: drainage

Performance

The 29.7 m maximum head is the head at near-zero flow, and the 2,260 L/min (about 135.6 m³/h) maximum capacity is the end point of the 50 Hz performance curve. The two do not occur together: actual flow falls as total head (static head plus pipe friction loss) rises. Select the pump from Tsurumi's 50 Hz performance curve using your system's total head; Hong Kong mains is 50 Hz, so do not use 60 Hz data. For lower head and flow, consider the 100B45.5 (5.5 kW, 26 m max head), which shares the same 100 mm discharge.

Optional accessories

Guide rail fitting TOS100B47.5: includes a duckfoot bend, guide support with bolts and nuts, guide hook, 5 m lifting chain with shackles and a JIS 10K flange. Guide pipes are not supplied.
Float switches: for level control through an external control panel. The MC-2 is a heavy-duty float switch with a shock absorber and selectable NO/NC contact, suited to liquids with suspended solids and scum; the MT-1 is an economy teardrop float with an integrated counterweight and SPDT switch, for emptying or filling control.
External control panel: three-phase pumps must be connected through a control panel with overload protection; a star-delta panel is available on request for this model.
Mating flange: the discharge is JIS 10K, so specify a JIS 10K mating flange for local pipework.

Safety and installation

Installation and electrical connection must be carried out by a registered electrical worker in line with local regulations. Earth the pump correctly and fit overload and earth-leakage protection in the control panel; set the overload relay to the nameplate rated current.
Check that the rotation direction is correct before running a three-phase pump for the first time.
After the built-in CTP trips, the motor may restart automatically once it cools. Always isolate the power before inspection or servicing.
Keep the liquid at or above the lowest running water level (335 mm) and avoid prolonged dry running.
The pump weighs 154 kg dry, so use hoisting equipment and lift it by its lifting eye or chain. Never lift it by the power cable.
Never submerge the cable end or cut or damage the cable sheath; the anti-wicking cable entry is a safeguard only.
Do not touch the pump or put your hands near the suction while it is energised. Follow confined-space and toxic-gas (e.g. hydrogen sulfide) precautions when working in sewage sumps; a guide rail fitting lets you lift the pump out for maintenance without entering the sump.
Use only for sewage and wastewater at 0–40 °C and pH 5–9. Do not pump flammable, explosive or strongly corrosive liquids.

Wear parts and routine checks

Main wear parts: impeller, suction cover and mechanical seals.
Check the oil condition and level in the oil chamber regularly (turbine oil ISO VG32, 4,800 ml) to protect the mechanical seals. If the oil is cloudy or contains water, have the shaft seals inspected promptly.
Regularly check the impeller for fiber wrapping or wear, and the cable sheath for damage.
