1. INTRODUCTION
ATTENTION: It is essential that anyone who will install, operate, service/maintain or be involved with this pump
shall read the whole of this manual before pump installation, operation or servicing/maintenance, as it contains
important safety information. Failure to follow these instructions could result in damage to the pump, equipment, or
injury to yourself or other people. Adherence to the procedures and specifications outlined in the following chapters
will assist in providing economical and reliable operation throughout the life of the pump. If service or repair other than
that described in this manual should become necessary, contact your supplier for assistance. Any pump returned to
the supplier for any reason must be fully cleaned and decontaminated and accompanied by details of what fluids have
been pumped, including full Health and Safety information (SDS sheets) if any of those fluids are hazardous.
DO NOT USE THIS PUMP TO TRANSFER LIQUIDS WITH A FLASH POINT BELOW 100°F (37°C) OR USE WHERE FLAMMABLE
VAPORS ARE PRESENT.
The 23920 Series self-priming Jabsco Flexible impeller pump is of
bronze pump head, nitrile flexible impeller, lip seal (2000 model)
and mechanical shaft seal (3000 model) construction powered
by a 12V or 24V DC motor for marine, domestic and industrial
applications, where short duration over running without flow is
a possibility. The ability to handle solids and robust construc-
tion suits marine/domestic waste discharge (including bilge
discharge), aqueous industrial fluid transfer and ability to handle
other fluids compatible with construction materials. The pump is
designed to be powered from fully charged batteries or other DC
supply with adequate amperage provision. Pump connections
are BSP/NPT thread, the pump being designed to operate with
1" reinforced hose. Dependent on system pressures, flows up
to 29.5 litres per minute at 3m H
per minute at 3m H
O (3000 model) can be expected with flow
2
declining as differential pressure across the pump increase. The
pump will reliably operate where differential pressures are at or
below 6m H
O (2000 model) or 12m H
2
running feature means the pump is not reversible, the discharge
being the vertical port. The pump comes with 250mm long
electrical connecting leads (2000 model AWG14 or 2mm²; 3000
model AWG12 or 3.3mm²).
2. SAFETY
Please keep this manual carefully and available to all operators.
Do not ignore safety instructions. Throughout this manual your
attention is drawn to certain procedures which must be followed
to ensure safe operation and servicing of this product.
•
Failure to observe the recommended safety procedures can
lead to material damage.
•
Do not use the pump if the end cover is removed, custom
fitted guards are missing or inlet & outlet pipework is not
connected.
•
Do not forget the hazards of moving parts, high fluid
pressure, extremes of temperature, hazardous liquids and
electricity.
•
Do not use the pump with fluids of flash point below 37°C
•
Always isolate and lock-out the pump before inspecting or
servicing pump.
•
Only qualified Service personnel should attempt to repair /
service the pump. Only use Original Equipment Manufactur-
er's Parts and Accessories.
•
Do not run the pump without suitable supervision as estab-
lished for safe working practices and company procedures.
•
Not to be used by children and non-authorized personnel.

ATTENTION
•
Always follow good working practice when using this
equipment.
•
Follow legislation applicable to your areas of operation.
•
Do not touch the motor surface during or after operation of
the pump as the surface can become hot.
•
The appliance is not to be used by children or persons with
reduced physical, sensory or mental capabilities, or lack of
experience and knowledge. Cleaning and user maintenance
shall not be made by children unless they have been given
supervision or instruction.
•
Children not being supervised should not play with the
appliance.
•
WARNING: all marine pumps discharging overboard must
be installed with overboard discharge well above static and
heeled waterlines. Flooding and death may occur.
•
California Proposition 65 warning: This product may contain
a chemical known to the State of California to cause cancer
birth defects or other reproductive harm.
•
The equipment is not spark, flame or explosion proof and
has not been designed for use in hazardous areas in terms of
the ATEX Directive 2014/34/EU.
•
Use recommended fuses.
3. OPERATING CONDITIONS
The pumps are designed using modern design techniques and
manufactured from high quality materials. However, there are
certain limitations to the operating conditions of the pump to
ensure long life and trouble-free running. During pump selection
and specification these limitations must be taken into account and
not be exceeded.
•
Ambient working temperature -5°C/23°F to 60°C/140°F.
•
All pump models are rated to handle pumped fluid tempera-
tures: 10°C (50°F) to 90°C (194°F).
•
Maximum suggested viscosity is 1000cP but care with pipe
losses is required.
•
Maximum prime height is 1.2m (4ft) for 2000 model and
2.4m (8ft) for 3000 model.
•
No leaks or blockages should be in the system. Inlet leaks
will degrade self-priming capability.
•
Initial pump priming must not last longer than 30s before
fluid enters the pump head providing impeller lubrication.
•
After initial prime and with flooded pump head, run dry
duration is 20 minutes (2000 model) and 10 minutes (3000
model).
