Tesca Basic Hydraulic Bench is of volumetric type and has been designed to provide a continuous and controlled supply of water to conduct various experiments using auxiliary modules in typical Fluid Mechanics and Hydraulics Laboratory. The unit is an ideal service unit for conducting student projects. Once filled, no external water supply is required. Water is recycled between the Experiment Module, Measuring Tank, and the Storage Tank by the Centrifugal Pump.
Several experiments in Fluid Mechanics and Hydraulics require a continuous and controlled supply of water. The Basic Hydraulic Bench provides a controlled recirculation water supply to conduct experiments.
The Basic Hydraulic Bench is a very important module and is recommended for all Fluid Mechanics and Hydraulics Laboratories in Educational Institutions. It is a basic module for flow-related experiments using auxiliary modules. Available in fiberglass or stainless steel or mild steel.
