2000 Series
rotary pumps incorporate a number of features, unique to Plenty Mirrlees
which make our rotary pumps some of the most versatile in the
marketplace. The range has been designed, through intensive
customer feedback, with the features that are essential to
the end-user - such as spares interchangability throughout
the range.
|
Variable
control flow rate from zero to maximum
|
Considerable
energy cost savings at reduced flow rates. External
pressure and flow control systems not required. Versatile
pump utilisation matching pump flow against system demand.
|
|
Fixed
speed drive
|
There
is no need to use expensive variable speed drives to
achieve variable flow, or reverse flow.
|
|
Comprehensive
flow control availability
|
Manual,
Remote Control and Automatic flow controls are available
to suit almost any application.
|
|
Plenty
Rotary Liquid Displacement Technology
|
The Plenty
pumping principle has lesser wear and lower maintenance
than other pumps in its class.
|
|
Versatile
design concept
|
Pump
arrangements suitable for viscosity applications from
1 cst to 1,000,000 cst
|
|
Robust
construction
|
Heavy
duty bearing arrangement designed for long operational
periods between routine maintenance.
|
|
Efficient
Suction
|
Low NPSH
required characteristics
|
|
Low Operational
Speeds
|
In addition
to long service life, the slow pumping action has a very
low shear rate, dramatically reducing or even eliminating
emulsification of the pumped liquid.
|
|
Low noise
|
Environmentally
acceptable for site operators.
|
|
High
volumetric efficiency
|
Low running
costs
|
|
Self
draining
|
Zero
retention, avoids cross contamination when installed
for multi product service.
|
|
Viscous
Liquid Handling
|
Unlike
some other designs, the Plenty rotary mechanism enables
the pump to operate at high viscosities whilst maintaining
high efficiency.
|
|
Mechanical
seals
|
The seal
housing is in accordance with the standard dimensions
of DIN 24960, and can therefore accomodate most brands
of mechanical seals, or API682 cartridge seals.
|
|
Heating
jackets
|
The pump
can be fitted with jacketed covers to allow heating by
hot oil or steam. (Electric heat tracing can be used
on non jacketed pumps).
|
|
2000 Series
parts interchangability
|
2000
series pumps share common parts, allowing minimal spare
part stocking requirements.
|
|
Relief
Valve
|
All 2000
series pumps are fitted with an internal pressure relief
valve to protect the pump from excess pressures.
|
|
API 676
|
Refinery
specifications and client special requirements can be
accommodated.
