3.1 Introduction
Grundfos pumps are carefully inspected and
tested before shipment. This pump should
provide long, efficient, trouble-free performance.
To ensure maximum performance and reliability,
please follow the simple instructions in this
manual.
When installing this pump, always follow basic
safety precautions and any federal, state, and
local requirements.
3.2 Delivery and handling
Examine the components carefully to make sure
no damage has occurred to the pump during
shipment. Take care to ensure the pump is NOT
dropped or mishandled; dropping will damage
the pump.
3.3 Pre-installation checklist
Before beginning installation procedures, the
following checks should be made. They are all
important for proper installation of the circulator
pump.
3.3.1 Applications
Model UP(S)15, 26, 43 and 50 series pumps are
generally designed to circulate water from +32
°F to +230 °F (0 °C to +110 °C) up to a
maximum pressure of 150 psi (10 bar). Some
models have temperature limitations which are
shown in Table A below. If required, a 50 % by
volume solution of ethylene or propylene glycol
and water can be used; however, a decrease in
pump performance may result due to an
increase in the viscosity of the solution. Check
with manufacturer for information regarding
suitability of pumping other liquids.
Closed systems
Model UP(S) 15, 26, 43 and 50 series pumps
with cast iron pump housings are designed to
pump water compatible with their cast iron
construction. They are recommended for use in
closed hydronic systems (i.e. airless, nonpotable water).
Open systems
Model UP(S) 15, 26, 43 and 50 series pumps
with stainless steel or bronze pump housings
are designed to pump water compatible with
their construction and can be used in both open
and closed systems.
3.3.2 Maximum water temperature
The maximum allowable water temperature is
determined by the ambient or surrounding air
temperature as shown in Table A.
