Vertical Inline Centrifugal Pump
Back pull out design for easy maintenance - allows the internals
to be removed without disconnecting the pump from the pipework.
Close coupled with lantern bracket to separate the pump head and
motor should the seal fail - prevents fluid from entering the
motor
Separate shafts in pump head & motor - no need to replace
entire pump & motor if the shaft wears
Pump manufactured in Spain with materials from own foundry
Marine type approved by all classification societies e.g.
Lloyds/ABS
CM with spacer coupling or easy maintenance of pump inner parts,
and flexible coupling for easy alignment of pump and motor -
reducing service time
CM and VR have additional bearing between pump and motor, to
share the strain of operation
Compact and space saving vertical design making it ideal for
installations which have limited space
Can be supplied with a vacuum or electric priming pump on
request for difficult suction conditions
Interchangeable spare parts with other Azcue models to reduce
stock holding
Wearing rings to improve pump efficiency & provide clearance
between the casing & impeller, preventing their wear, meaning
only the less costly wear rings need replacing

Benefits -• Manufactured in Spain by manufacturer with over 100
years' experience, using materials from their own foundry for
complete control• Marine type approved by all classification
societies e.g. Lloyds/ABS for independent verification the pump
meets quality standards• Compact and space saving vertical design
making it ideal for installations which have limited space• Close
coupled with a lantern bracket to separate the pump head from the
motor, so should the seal fail fluid is prevented from entering the
motor and causing damage to this part• CM comes with spacer
coupling for easier maintenance of the pump's inner parts without
having to remove the motor or the suction/discharge pipework• CM is
fitted with a flexible coupling meaning the pump and motor are
easily aligned reducing service time• CM and VR has an additional
ball bearing between the pump and motor to share the strain of
operation, increasing service life and reducing maintenance costs
cause by wear. CM FR has a triple ball bearing design to further
reduce load.• Interchangeable spare parts with other Azcue models
to reduce stock holding required• Spares available for a minimum of
15 years after model discontinuation for long term servicing even
if the pump is no longer produced• Bearings are greased for life
with long service intervals to reduce maintenance costs – bearings
replaced at 25,000 hours• Back pull out design for easy maintenance
- allows the motor to be removed without disconnecting the pump•
Wearing rings to improve pump efficiency and provide clearance
between the casing and impeller, preventing their wear, meaning
only the less costly wear rings need replacing• Separate shafts in
pump head and motor - no need to replace entire pump and motor if
shaft wears, saving costs• Motors are tropicalized as standard for
operation up to 45ºC meaning the motor is designed continue
operating during higher than average temperature• ATEX approved
version for hazardous environments
