AXIAL FLOW IMPULSE TURBINE APPARATUS Model FM 35

Sci-tech Axial Flow Impulse Turbine Test Apparatus Model FM 35 consists of an inlet manifold which supplies water to four jets which are equally spaced around the turbine runner. Each of the jets can be individually controlled using ball valves. The runner itself is mounted on a horizontal shaft with a clear acrylic splash guard to allow maximum visibility of the workings. The unit incorporates a pressure sensor to measure the inlet condition of the water. This pressure can be accurately controlled using the software supplied with the service unit.

Size: 120cm x 60cm x 80cm (LxWxH)
Weight: 40 kg

Item Description

Sci-tech Axial Flow Impulse Turbine Test Apparatus Model FM 35 is widely used for pumping liquids in several applications including domestic, industrial, irrigation and drainage. The Impulse Turbine is a small-scale impulse turbine unit which is designed to be used in conjunction with the service unit. An impulse turbine uses the momentum transferred from the impact of a jet of water onto the turbine blades to generate power The Impulse Turbine is an experimental set-up necessary for any Fluid Mechanics and Hydraulics Laboratory of an educational institution.
