The Tsurumi - HS2.75S Submersible Pump - 10-10-1237 is a versatile and reliable piece of equipment designed for various drainage Uses in environments like construction, industrial, and domestic settings. This particular model, with part number 10-10-1237, features a pendant float switch and operates on a 230V power supply.
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.
