Product Overview

The TSURUMI 100BA43.7 is the official "Automatic Model" of the B-series non-clogging submersible sludge pump, with a 100mm discharge bore. It shares the identical 4-pole, 3.7kW three-phase induction motor and non-clog channel-impeller core with the standard 100B43.7, allowing solids to pass through without jamming. The distinction from the standard 100B43.7 is that the 100BA43.7 has a built-in automatic float switch, allowing it to start and stop automatically based on sump water level without an external level controller - which makes it slightly taller and heavier than the standard model. This "Automatic" naming convention matches its 2.2kW sibling, the 100BA42.2 - both are officially listed, factory-catalogued models within Tsurumi's B-series lineup, not unofficial or mislabeled variants. The pump body is cast from grey iron and fitted with a dual mechanical seal (silicon carbide) running in an oil bath for extended seal life. Designed for fully submerged, standalone automatic operation in sump pits, sewage wells and construction dewatering pits, the 100BA43.7 is a mid-size automatic workhorse for commercial and industrial sewage/wastewater transfer.
