Peristaltic Pump Learning System versatile pump keeps fluid uncontaminated as it moves through the system by utilizing a tubing system that prevents direct contact with the pumps working parts. The Peristaltic Pump Learning System also discusses peristaltic pump components, how to reduce pulsation, how to calculate and adjust the flow rate, and how to select proper tube sizes. The Peristaltic Pump Learning System covers the function, operation, and maintenance of peristaltic pumps, which are used in a variety of applications within the chemical, food, pharmaceutical, and biotechnological industries. As an example, peristaltic pumps are used to filter and circulate blood throughout the body during heart surgery.
The Peristaltic Pump Learning System industrial-grade components are the same as those used in the field, so learners will gain experience and practice on actual, real-world mechanisms. The Peristaltic Pump Learning System features a foot-mounted peristaltic pump with polycarbonate housing and steel pump head, a maintenance key tool, and a piping network. Once completed, learners can proceed to additional pumps like the Piston Pump and the Gear Pump. Gear pumps transfer fluids under pressure and are used in hydraulic systems, pressure washing, and liquid recirculation. Piston pumps are used in water, soap, and detergent applications to produce high pressure fluid flow.
Features:
Industrial Quality Peristaltic Pump
Quick Connect Piping Connections
Mounting Compatible with Workstation.
A dye injection system allows four dye lines to be generated which highlights visualisation of flow lines and allows flow nets to be drawn for seepage analysis. Scales on the front panel assist in the preparation of models. Permeability Apparatus consists of a framed glass tank, of internal dimensions 1900 mm long by 530 mm high and 130 mm front to back. The base of the tank incorporates fourteen pressure tappings at 100 mm pitch, the tappings are specially designed to prevent the ingress of sand particles. Flexible tubes connect the tappings to two multitube manometer banks scaled 0 to 500 mm, for measure-ment of the water table height along the tank. The tank is mounted on a fabricated steel frame fitted with castors and levelling feet. The front, back and ends of the tank are of clear toughened glass giving scratch free visibility without the risk of abrasion of the inner surfaces by the permeable medium. Scales on the front panel assist in the preparation of models and in the prepara-tion and recording of flow nets. Washed silica sand graded 0.2 mm to 1.0 mm should be used as the permeable medium which must either be ordered separately from supplied by the end user. Coarser material may also be used. An activated carbon decolourising filter is provided in the sump tank to prevent the progressive dis-colouration of the water by prolonged use of dye.

A bed of granular medium (usually sand, but other materials can be used such as Ballotini or anthracite) is placed in a readily demountable tube through which water can be made to flow in either a downwards or upwards direction.
The test section tube and all tubing connections are transparent so that operation can be observed and the presence of air bubbles easily detected. All metal fittings are corrosion resistant.
Pressure drop across the bed can be measured either by a 0.5m length water differential manometer or a 0.5m length Mercury manometer (see recommended accessories), depending on the magnitude. Valves are fitted for isolation of various parts of the circuit, together with air release valves.
Flow from a laboratory tap passes through a constant head tank, which also allows air bubbles to be released, and is controlled by hand with a needle valve. The rate of flow is indicated by a variable area meter.
No power connections are required and the whole apparatus can be lifted and transported by one person. Test material (Ballotini) for the packed bed is supplied but Mercury for the manometer is not included.
Experiments:
Flow under a sheet pile and determination of critical seepage force at which piping occurs
Flow through an earth dam with and without a toe drain
Draw down in horizontal flow (simulation of ground water flow into a river or well)
Determination of seepage beneath a structure
Construction of flow nets and determination of coefficient of permeability
General studies of seepage and drainage
Seepage flow under an impermeable dam
Flow through a porous medium
Determination of uplift pressures on structures such as building foundations.
The Iengine rig is equipped with a fully functional original engine on the current technological development. The circuit diagrams and repair manuals are included on the supplied CD. Diagnostic sockets are fitted to the engine rigs as appropriate. All rotating parts arefully guarded. The motor is mounted on a movable aluminum frame. The permanently installed test box with 4mm sockets with direct access to all154 ports of the engine control unit and the adapter cables offer thepossibility to represent 20 realistic faults and malfunctions, to locate andfix it. The engine rigs offers an enhanced training resource, hands-ontraining with real components, greater understanding for the student withoutthe constraints of the modern motor vehicle. In addition, the motor training stand has simulator components (5), an emergency-off switch as well as a table to place a laptop for instance.
