Medium UPM

12. Performance curves

Curve conditions

The guidelines below apply to the performance curves
on the following pages:
• Test liquid: airless water.
• The curves apply to a density of 998.21 kg/m
liquid temperature of +20 °C.
• All curves show average values and should not be
used as guarantee curves. If a specific minimum
performance is required, individual measurements
must be made.
• The curves apply to a kinematic viscosity of 1.004
2
mm /s (1.004 cSt).
• The conversion between head H [m] and pressure p
[kPa] has been made for water with a density of
3
1000 kg/m . For liquids with other densities, e.g. hot
water, the outlet pressure is proportional to the
density.
• Curves obtained according to EN 16297.
• Medium UPM with PWM signal connection are
designed to be speed controlled by an external
system controller. Therefore, EEI and P
different pump heads (pumps without pump
housings) are measured to be in compliance with
the Ecodesign requirements of regulation EC/622/
2012 with a reference housing in accordance with
EN 16297-3.
• It is not obligatory to show P
indication on the yearly expectable average power
consumption.
• The performance of PWM controlled pumps is
measured with A profile (heating) at eight PWM
values: 5 % (max.), 20 %, 31 %, 41 %, 52 %, 62 %,
73 %, 88 % (min.).
• C profile curves are measured mirrored with 95 %
(max.), 80 %, 69 %, 59 %, 48 %, 38 %, 27 %, 12 %
(min.)
• Maximum curves are limited by speed and power
• Other curves for different control signals or OEM
housings are available on request.
