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.

Constant running water level

Features and Benefits
  • Effective motor cooling
    The outlet channel is part of the motor housing and effectively cools the motor
  • Overheating protection
    Pump stops at excessive temperatures, automatically cools down, then starts again
  • Automatic level control
    Optional float switch and level sensor, which controls the operation of the device depending on the water level
  • Phase reversal protection
    Ensures correct direction of rotation
  • Models with agitator
    Minimize clogging, ensuring free flow through the pump
  • Rigid construction
    Pump body and motor made of cast iron or stainless steel
