Screwpump Series

Screwpump Series
ACE3
Product description
Flow volume: 15-160 l/min
Max differential pressure: 16 bar
Applications: Lubrication, circulation and transfer
Technical data
The ACE pumps are used for a number of
different fluids:
Lubrication oil, fuel oil, vegetable oil,
hydraulic oil and other hydraulic fluids,
glycol, polymers, emulsions, and any nonaggressive fluid with sufficient lubricating
properties.
When so required the ACE pump may be
certified according to any of following
classification societies: DnV, BV, LRS, ABS,
RS, GL, RINA, KR, NK or CCS.
Typical applications are:
• Lubrication of diesel engines, gears,
gas and steam turbines, hydro turbines
and paper machines.
• Circulation for cooling and filtration in
large machineries, hydraulic systems and
transformer oil for insulation in transformers.
• Transfer onboard ships, in oil factories,
refineries, tank farms etc.
• Fuel supply duties for diesel engines.
Discharge pressure
Maximum discharge pressure is 16 bar.
Differential pressure
Maximum differential pressure is 16 bar but is reduced at low viscosities as shown in the
table below.

Pressure relief valve
Drive
The pump is equipped with an integral
pressure relief valve with internal return,
limiting the differential pressure across the
pump and protecting the pump, should the
discharge line be blocked. The valve is
adjustable for different opening pressures.
The value of the pressure limit can be set at
the factory and should be adjusted at installation (see Installation & Startup
instruction for low-pressure pumps).
The maximum pressure ackumulation
varies with pump size, speed and viscosity,
but will normally not exceed 4 bar. The
characteristic of the valve allows the valve
to be used as pressure regulating valve
when not too high demands on pressure
modulation are required. The valve has a
maximum set pressure of 16 bar.
The pump is designed to be connected to
an electrical motor by a flexible shaft
coupling.

Max speed limit
The maximum speed is 3600 rpm. For
higher speeds contact IMO AB.
Rotation
The ACE pump is designed to operate in
one rotational direction only, as standard
clockwise when facing the shaft end.
Pumps for CCW operation can be
delivered on special request. For shorter
periods of time, a few minutes for emptying a
discharge line, the pump may be operated in
reverse direction, provided the back
pressure is limited to 3 bar.

Fluid viscosity
Mounting attitude
For type NVBP:
1.6 up to 800 cSt.
For type NTBP:
1.6 up to 1500 cSt.
For type NQBP:
1.6 up to 1500 cSt.
For higher viscosity contact IMO AB.
The ACE is mounted vertically with the
shaft pointing upwards or horizontally
with pipe connections facing upwards or
sideways. On special request a pump for
horizontal mounting with pipe connections
facing downwards can be delivered.
Fluid temperature
For type NVBP: -20°C up to 110°C.
For type NTBP: -20°C up to 155°C.
For type NQBP: +5°C up to 155°C.

For bare shaft pump
A typical sound level from a pump with
standard driver is 58 dB(A). This value
refers to free field conditions at 5 bar, 2940

Installation
The ACE-pump is designed to be flangemounted to an electric motor via a
connecting frame and a flexible shaft
coupling and has an angle bracket for
mounting horizontally and vertically, see
mounting instructions. Two pump units can
also be mounted to a double assembly on a
common frame with inlet and outlet pipe
connections. The double assembly saves
space and facilitates installation,
maintenance, service and supervision. See
Product description for T4.

The pump unit, pump with connecting
frame and motor, is designed to work in an
air temperature between +2 °C and +40 °C.
This with a maximum humidity of 80 %.
For other environmental conditions,
please contact IMO AB. The pump body,
however, can be heated to maximum
fluid temperature.
For more information about installation,
see the Installation and Start-up instruction
for low-pressure pumps.

SealGuard enhances shaft
seal life when handling
Heavy Fuels, having a
tendency to form hard
deposits impairing the
shaft seal performance.
