Reliability is a key factor
Reliable water supply systems are a key
factor in our modern society. Grundfos CR pumps are constructed as
heavy duty units, capable of withstanding the wear and tear resulting
from repeated stop-and-start operations as well as extended periods
of continuous running - typical of water works.
Low running costs
Supplying water at the lowest possible price is another
essential requirement, resulting in increased demands for pump efficiency
as well as low running and maintenance costs. With their high efficiency
ratios (greater than 80%) Grundfos CR pumps are designed to meet these
demands.
Easy servicing
CR models are constructed with long-term use in mind,
featuring easily replaceable wear parts and servicing that requires
no special tools. The mechanical shaft seals are available as O-ring
or bellows for models up through CR16, and the larger models - CR32
and up - are fitted with cartridge shaft seals which can be replaced
without disassembling the pump (or removing the motor for 15-60 HP).
The optional Grundfos hybrid seal offers protection of the seal faces
against occasional dry run.
High user comfort
Due to the optimized pump characteristics of Grundfos
CR pumps, end users will enjoy maximum comfort. Minimal levels of
noise and vibration allow the pumps to be installed practically anywhere.
Complete booster systems
Grundfos offers a wide range of fully integrated
booster systems, based on the CR program. Grundfos BoosterpaQ® systems
incorporate advanced controls for adjusting and monitoring the pumps.
