Product Details:
Minimum Order Quantity1 Piece

Hydraulic Ram Test Rig Apparatus consists of a close circuit through which water is circulated continuously by means of a centrifugal pump of 25 mm x 25 mm with 0.5 H.P. motor to make the supply from sump tank. A sump tank 125 cm long, 80 cm wide and 40 cm high fabricated on M.S. angle frame with 3 mm thick M.S. sheet is provided. Inside of the tank is lined with FRP. A drain valve of 15 mm size is provided in the bottom of the tank. A supply tank 50 cm x 50 cm and 100 cm high fabricated with S.S. sheet with over flow arrangement, gauge glass tube and 15 mm size drain valve is provided. Inside of the tank is lined with FRP. The tank has the provision for fixing the supply pipe of 50 mm dia of which other end is connected to the ram. The tank is supported on a stand fabricated from M.S. angle.

For the supply head of 2.5 m, the discharge head of the ram will be 15 m (approx.) the discharge will be 360 LPH. A pressure gauge is provided with a regulating valve on the delivery side of the ram (delivery pipe is of 15 mm dia) so that much greater head of water can be observed and obtained by the adjustment of the shifting valve provided in the ram assembly. Lifted water can be collected by the help of a collecting tank of 30 cm x 30 cm and 30 cm high. The tank is provided with gauge glass tube, flow diverting arrangement and a drain valve of 25 mm size. Waste water can be measured by the help of another collecting tank. The tank is provided with gauge glass tube, flow diverting arrangement and a drain valve of 15 mm size. Necessary G.I. piping system & flexible pipe of suitable size, necessary fitting and control valve are provided with the apparatus.
