Submersible dewatering pumps – SB series
Tapflo SB pumps are made of rigid cast iron, the pump operates smoothly day after day. The pump has a significantly increased maximum submersion depth thanks to the use of a mechanical seal, which is resistant to high pressure. The semi-open impeller made of high-chrome alloy with a wear plate (ductile iron) ensures resistance to abrasive materials.
The pump motor is hermetically sealed and has built-in thermal protection. Sizes from SB2-22 to SB4-37 can be equipped with a level control sensor marked with the symbol (E).
Models with discharge ports up to 80 mm/ 3” include a two-position outlet connection, allowing the user to set the outlet hose in a horizontal or vertical direction to avoid kinking or bending the hose. These same models are supplied with a BSP thread adapter.
