The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas.A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. All the system components are kept ready to hand and well protected in a housing system.The multi-step and shift gears in are based on those of a conventional lathe. The step gear unit is very similar to the primary drive on a pillar drill.

The loss is measured by differential pressure using manometers. Pressure tapping is by valves with quick connection. The unit is on a steel frame on wheels. All pressure taps are connected by flexible hoses to a set of specially arranged manifolds such that differential pressure across any component can be measured simply by opening valves without removing the hoses.
Piping Loss Test Set Small is a self contained unit for studying the friction loss in pipes, pipe fittings and valves at various flow rates.
The unit consists of a pump, a storage tank and a water proof panel on which all friction loss components are arranged.
The Marcet Boiler includes a special-purpose glass window. It allows students to see the internal construction of the vessel, to see the boiling process and to check the water level. The electrically-heated boiler holds water. As the water temperature increases, so does the pressure in the boiler. The apparatus consists of a rigid frame containing an insulated pressure vessel and an instrumentation and control unit. The Marcet Boiler is a simple experiment to show the relationship between pressure and temperature for saturated steam for comparison with published results. The frame also has extra space for the optional interface. A digital display shows the values in both SI and traditional units. A transducer and a thermocouple measure the boiler pressure and temperature.

The programme of exercises enables familiarisation with six different drive implementation and analysis methods: understanding the brief and the drawing, assembly, setting, adjusting, testing, and making calculations. This laboratory system is used to introduce the basics of gearing and the correct method of assembling drive elements. A robust tubular steel frame with a square profile and bearing elements provide the accuracy for the setting of precise gearing. All the system components are kept ready to hand and well protected in a housing system. Offers three assembly kits in this product series, each focussing on different aspects. Each kit is used entirely independently of the other kits within the series. The flexibility of the set-up and the modularity of the components simplifies experimentation and implementation of the students' own ideas.

Compact Series And Parallel Pump Test Set Multi Speed is a self contained bench top unit for studying the series and parallel pump characteristics at three different speeds. By manipulating flow control valves, each pump can be operated individually or both pumps connected in series or parallel. The unit consists of two centrifugal pumps with multi speed motors and a storage tank on a steel base, and measuring instruments.
Experiments:
Flow rate vs head at a fixed speed for two pumps connected in series or parallel.
Flow rate vs head at various speeds for individual pump.
The pump has a very simple and robust set-up and never the less has a very high capacity. The pressure and suction valve and the oil duct are cut open. If the rotor is turned, the enlargement and reduction of the working area can be seen particularly well, as can the contact of the slide shoes in each position of the vane. In order tosupply a vacuum for brake boosters, vacuum pumps are used in both diesel and,increasingly, in Otto engines.
