The Tsurumi - HS3.75S Submersible Pump - 10-10-1003 (SKU 10-10-1003) is a high performing single-phase submersible pump designed for efficient water removal in challenging environments. This 110V model features a pendant float switch for automatic operation, making it ideal for various industrial and construction Uses.
For the automatic control of water levels, theHSseries is available with sensor and float switches: The Sensor switch has two 304 Stainless Steel probes that are encapsulated in moulded rubber and it is designed for portable Uses. The compact design and precise water level control also makes it suitable for fixed installations and narrow or shallow sumps. During use, when both probes touch water, the pump will start and continue to operate for one minute after the water level drops. However, if the water touches both probes again within this time, the pump continues pumping for another minute and will continue like this on demand, so keeping the water level constantly below the level of the probes at all times. The off level can be as low as the level of the water entry of the volute at 50mm, depending on the sump size or area being drained. Probes can be lengthened by 70mm or 170mm, with optional extensions, to enable a lower "on" and "off" level.
Thefloat-switch has a power cable connected to a waterproof case that contains a ball bearing actuated switch and is designed for portable and fixed installations. The cable is clamped to the pump, with a small amount of adjustment to alter the "on" and "off" level.
Thefloat-switch has a switch actuated by a floating cylinder, housed within a tube. Compact, with fixed "on" and "off" levels for precise level control, it is intended for narrow sumps and fixed installations.
