Technical data
Flow rate:
up to 200 gpm (45 m
3
h)
Head:
up to 60 ft (18 m)
Liquid temperature:
–13 to +284 °F
(–25 ° to 140 °C)
Max. operating pressure:

Motor sizes (single-phase): 0.33 to 1.5 hp
Construction
TPE Series 1000 pumps are based on TP pumps.
The main difference between the TP and the TPE
Series 1000 pump range is the motor.
The motor of TPE Series 1000 pumps has a built-in
variable frequency drive designed to continuously
regulate the pressure and the flow.
TPE Series 1000 pumps are suitable for applications
where you want to retrofit a sensor in order to control
e.g. the pressure, temperature, flow etc. at some
arbitrary point in the system. Sensors shall be supplied
by others.
For further information on construction and materials
of TPE Series 1000 pumps, see page 12 and 13.
Applications
TPE Series 1000 pumps have integrated speed control
for automatic adaptation of performance to current
conditions.
This ensures that the energy consumption is kept at a
minimum.
TPE Series 1000 pumps can operate in any duty point
within the range between 25 % and 100 % speed.
In the QH-chart the 100 %-curve corresponds to the
curve for a pump fitted with a standard fixed speed
motor.
Depending on the nature of the application, TPE
Series 1000 pumps offer energy-savings, increased
comfort or improved processing.
The pumps can be fitted with sensor types meeting the
requirements mentioned below:
