Tsurumi - LB 480 Submersible Pump - With Float Switch - 230V

LB 480 automatic submersible Pump - 10-10-1203 c/w F-type float switch, 230V. The LB range of submersible drainage pumps are compact, lightweight and powerful. They are suitable for ground water and water containing sand and silt - maximum solids handling of 6mm.

For the automatic control of water levels, LB480 and LB800 are available with sensor and float switches:

Theswitch 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 suction cover at 20mm, depending on the sump size or area being drained. Probes can be lengthened by 70mm or 170mm, with, 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.

The float-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.
