Dual Pump Alternating Controller for Water Systems

ZBS-2 Dual Pump Alternating Water Pump Controller   This ZBS-2 water pump controller is an intelligent electronic control device developed specifically for dual pump systems. It features alternating operation of dual motor water pumps and is widely used in municipal drainage, sewage pump stations, high-rise water supply, water storage tank control, industrial water supply and drainage, and other scenarios that require dual pump collaboration. The device can be powered on to achieve cyclic start stop, supporting intelligent logic such as synchronous start and fault pump replacement. It has three built-in working modes, namely one main and two backup, two main and one backup, and one main and one backup, which can be freely switched according to the on-site working conditions and adapted to different drainage and water supply needs. The product is compatible with multiple signal control methods, supporting float ball, pressure gauge electrical contacts, and electrode signal access. It i…
