When lifted, a twist of 90° at the actuator will retain the dump valve in the open position. Lifting the actuator opens the dump valve allowing the water to return to the sump for recycling. A remote sight tube and scale, is connected to a tapping in the base of the volumetric tank and gives an instantaneous indication of water level.Ī dump valve in the base of the volumetric tank is operated by a remote actuator. This tank is stepped to accommodate low or high flow rates and incorporates a stilling baffle to reduce turbulence. Water discharging from the accessory on test is collected in the volumetric measuring tank. In addition to the hose connector the channel incorporates a pair of wall slots and a weir carrier for use with accessory F1-13. The moulded bench top incorporates an open flow channel with ridges at either side to support the accessory on test. A drain valve is incorporated in the end wall of the sump tank to facilitate emptying.Įlectrical supply to the pump motor is via a switch and RCD mounted in the recess on the front of the bench. No hand tools are required for either of these operations. Special purpose terminations may be connected to the pump supply by unscrewing the hose connector. The hydraulics bench consists of a moulded plastic sump tank which supports GRP bench top incorporating a flow channel and volumetric measuring tank.Ī self -priming centrifugal pump and draws water from the sump tank and delivers to a quick release hose connector in the flow channel via a panel mounted control valve.
