2 General information
2.1 General information
The DuraCirc pump supplied is a positive displacement circumferential piston pump, which may be
supplied with or without a drive unit. The drawing shown indicates main components of the pump unit.
The DuraCirc range has a universal gearbox design which enables the flexibility of mounting pumps
with the inlet and outlet ports in either a vertical or horizontal plane. The port orientation, vertical or
horizontal, may be changed by moving one of two available bolt-on feet on the gearbox. Port
orientation should be specified when ordering, but the alternative foot design allows pumps that are
already installed being changed should the need arise.

Pump duty conditions
The pump should only be used for the duty for which it has been specified. The operating pressure,
speed and temperature limits have been selected at the time of order and MUST NOT be exceeded.
These details are stated on the original order documentation and if not available may be obtained
from your supplier quoting pump model and serial number.

EN
Noise levels
Under certain operating conditions pumps and/or drives and/or the systems within which they are
installed can produce sound pressure levels in excess of 80dB[A]. It recommended that the noise
level is measured during commissioning, running on normal operating conditions and appropriate
personal protective equipment used where necessary.
Vibration Limits
Bare shaft pump units have been tested and found to be within the limits published under ISO
10816-7 Category 2 under normal operation conditions. Actual vibration of mounted units can be
effected by numerous external factors such as mounting method, foundation, alignment, speed and
duty point. As such, we recommend the maximum operating limit of 8.5 mm/s RMS with a trip limit of
10.6 mm/s RMS as per ISO 10816-7 Cat. 2 is observed in any monitoring equipment if used.
