Description Learning outcomes
A compact, mobile and fully self-contained centrifugal Comprehensive demonstrations and investigations into a
pump test set that allows students to find the centrifugal pump including:
characteristics of a centrifugal pump. It also allows them
• Centrifugal pump performance and characteristics,
to see (and hear) cavitation and understand the use of a

Venturi meter and differential pressure measurement to
find flow rate. • Non-dimensional performance characteristics
A motor mounted in bearings drives the pump. The pump • Flow measurement using a Venturi tube
draws water from the integral reservoir. The water travels
• Demonstration of cavitation
up through a valve and filter, through an inlet valve to
the pump body, then out through a delivery valve. It then
passes through a Venturi meter and returns to the reservoir Standard Features

the water vapour bubbles form in the pump at cavitation. • Made in accordance with the latest European Union
The optional stroboscope makes the effect easier to see. directives

speed. A display on the Motor Drive shows speed and (frame-mounting version)
torque and automatically calculates and displays true
‘shaft’ power. • Stroboscope (ST1)
The differential pressure across the Venturi gives flow rate. • Analogue Pressure Display (AP1)
The adjustable inlet and delivery valves allow students to
create different operating conditions.
TecQuipment supply a Digital Pressure Display (DP1) as
standard but offer an optional, additional easy-to-read
Analogue Pressure Display (AP1). Both instruments display
the inlet pressure, delivery pressure and differential
pressure across the Venturi. The Analogue Display is
more visual, but the Digital Display increases ease of
measurement, and allows connection to TecQuipment’s
frame-mounted Versatile Data Acquisition System
(VDAS-F, available separately).
The equipment can use both analogue and digital
instrumentation at the same time, enabling students to
compare the different pressure measurement methods.
