7.7 Ordering parts
Grundfos Pumps has over 90 years of experience in the design,
manufacture, and application of centrifugal pumps and pumping
systems. Grundfos's commitment to state-of-the-art pump design
and quality manufacturing assures maximum user benefits with
optimum equipment life at lower cost.
Grundfos's commitment to their customers continues through an
extensive service organization. Highly trained technicians can
assist customers with initial startup, troubleshooting, repair, and
system analysis.
PACO maintains an extensive stock of replacement parts and
parts kits for our most popular model pumps. Shipment of these
parts is normally made within three days after receipt of an order.
On larger pumps, where it is impractical for our factory to
inventory low usage parts, replacement parts are normally
manufactured and shipped within 15 working days of receipt of an
order. In order to reduce pump repair time and shorten
inconvenient pump service interruptions, it is suggested that the
pump user stock spare parts. For suggested spare parts see
Replacement Parts Guide A1b.2, attached, and contact your local
PACO Sales Representative (see back cover for the number of
your nearest PACO Sales office). Since spare parts requirements
and quantities vary for specific pump constructions, allow your
PACO Representative to help in defining your spare part
requirements. To ensure that the proper replacement parts are
ordered for your particular pump model, when you call:
• Identify all pertinent data from the pump name plate (see
Pump Identification ). This should always include the pump
Catalog or Model Number, and the pump Serial Number.
• For replacement impellers, also include from the nameplate
the operating conditions (GPM and TDH) and the impeller
diameter.
• Identify all parts by item number and description as indicated
by the appropriate assembly drawing in this manual, for your
particular pump model.
Warning
Coupling guard must be reinstalled and in place
prior to operation.
