Product Overview

The TSURUMI 100B43.7H-E1 is a High-Head (H) variant of the B-series non-clogging submersible sewage pump, with a 100mm discharge bore, a 3.7kW, 4-pole three-phase motor, and a semi-open single-channel non-clog impeller built for wastewater applications where extra head is required compared with the standard-head 100B43.7. The "-E1" suffix denotes the automatic-operation variant with a built-in float switch, which starts and stops the pump according to water level, making it suitable for sumps and pump stations that need to run unattended for long periods.

TSURUMI B-series 100B43.7H-E1 non-clogging sewage pump

100B43.7H-E1 semi-open single-channel impeller structure

Key Features

High-Head (H) impeller design delivers greater total head than the standard model of the same output, suited to discharge lines with larger vertical lift
Built-in float switch (E1 automatic model) starts the pump when water reaches the set level and stops it automatically at low level
Semi-open, single-channel non-clog impeller passes solids and stringy material commonly found in sewage without clogging
Double mechanical seal in a separate oil chamber — upper faces ceramic + carbon, lower faces silicon-carbide (SiC) vs SiC — with Tsurumi's patented oil lifter maintaining lubrication even at low oil level
Built-in thermal motor protector automatically cuts power on overheating or overload, protecting motor life
Anti-wicking cable entry prevents water ingress into the motor via capillary action; IP68 protection rating

Applications

Sewage treatment plants / lift stations: municipal sewage transfer and intermediate pumping stations

Building / estate sumps: collection pits that need extra head to discharge to ground level or upper drainage systems

Industrial wastewater transfer: automatic discharge of solids-laden wastewater from factories, car washes, and similar sites

Construction sites / tunnels: temporary dewatering that must start and stop automatically without an attendant
