10.1 Conceptualisation
A pumphead is pictured in all illustrations in this chapter for conceptualisation of the final installation. A
pumphead should only be installed after physical (this section) and electrical installation (
(Electrical power)" on page 55
) have taken place.
NOTICE
The weight of the pumphead makes the drive unstable, resulting in the pump toppling over to one side.
Always anchor the pump to its mounting surface prior to installation of the pumphead.
10.2 Location
The product may only be installed such that it cannot exceed its environmental and operation limits.
10.2.1 Environmental and operating conditions
The pump is designed for use in the following environment and operating conditions:
Ambient temperature range
4 °C to 45 °C (39.2 °F to 113 °F)
Humidity (non-condensing)
80 % up to 31 °C (88 °F), decreasing linearly to 50 % at 40 °C
(104 °F)
Maximum altitude
2,000 m, (6,560 ft)
Pollution degree of the intended
environment
2
Noise
<70 dB(A) at 1 m
Maximum fluid temperature
SEBS pumpheads: 40 °C (104 °F)
Santoprene pumpheads: 45 °C (113 °F)
PU pumpheads: 45 °C (113 °F)
Environment
Indoor and limited outdoor
NOTE18
Chemical compatibility is dependent on temperature. A procedure for checking chemical
compatibility is provided in
"19 Chemical compatibility" on page 202
NOTE19
Under certain conditions the pump is suitable for limited outdoor use. Contact your
Watson-Marlow representative for advice.
NOTE20
Protection of drive to NEMA 250 with the HMI cover (optional accessory) installed.
