A floor sump unit featuring a 55L Polypropylene Tank with ribbed sides for added strength, plus the ribs will anchor the tank if it is partially concreted in place. The lid has a 315mm dia opening and it is strong enough to walk on. The large opening allows easy access into the tank for service. The tank has 2x 110mm i.d. pipe sockets that will accept pipes from any in-ground drainage system. Installed in the tank is our type TPO1376 drainage pump with integral on/off float switch, a 350watt 230v single phase motor, with built in overload & auto-reset, and with 10m cable with std 3pin plug. Pump max head 7m, and max flow is 6500L/Hr. On the pump outlet is fitted a brass non-return valve, and pipe nut for easy removal/inspection. The non-return valve prevents back-flow when the pump stops. Tank outlet pipe connection is screwed 1"BSP, into which you can screw in a wide variety of fittings/pipe. A fiber-glass grate can be supplied at an extra cost of $23.00. Extra cost for a 230mm high riser for deeper installations is $35.00. A 550w type TPO1118P pump to pass small solids is an extra $15.00. If you want to pass large 32mm dia solids, we can fit a 40mm outlet pipe with 40mm non-return valve at an extra cost of $60.00
