TBZ-series robust pumps are best suited for draining in civil engineering, but can be also used for general pumping purposes. Motor and pump casing is made of rigid cast iron for long-lasting durability. Maximum submersion depth is greatly increased due to mechanical seal resistant to high pressure. Semi-open impeller made of high chrome alloy in combination with wear plate (ductile iron) achieves superior durability. Effective motor cooling due to execution of discharge channel integrated into the motor housing. Space saving design due to a top outlet. Discharge outlet from 50mm to 150mm, Motor from 1,5kW to 15kW. Hermetically sealed motors below 15kW are equipped with build-in thermal protection.
