PRODUCT DESCRIPTION

Electric motor driven, close coupled, single stage, end suction configuration and of
centrifugal design with integral Jet injector.

APPLICATION

The Jet Pump range is designed to pump clean fresh water.
The pumps can be used for applications such as water transfer and distribution, pressure
boosting and irrigation. The pump can be used for portable applications and is also
suitable for self-priming (after initial priming) installations using the optional suction hose/
footvalve assembly.

z This pump set must not be used for any other

application without the written consent of Stuart
Turner Limited and in particular, must not be
connected directly to the mains water supply.

z This appliance can be used by children aged from

8 years and above and persons with reduced
physical, sensory or mental capabilities or lack
of experience and knowledge if they have been
given supervision or instruction concerning use of
the appliance in a safe way and understand the
hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall
not be made by children without supervision.

z Children should be supervised to ensure that they

do not play with the appliance.

Please read installation details carefully as they are intended to ensure this
product provides long, trouble free service. Failure to install the unit in
accordance with the installation instructions will lead to invalidation of the
warranty.

STORAGE

If this product is not to be installed immediately on receipt, ensure that it is stored in a dry,
frost and vibration free location in its original packaging.

1 IMPORTANT FACTS: READ BEFORE COMMENCING PUMP INSTALLATION

A. Water storage capacity.

1.11 The cold water storage capacity must be sufficient to meet the flow rates
required by the pumped equipment and any other water using fittings and
appliances, which may be operated simultaneously.

1.12 Ensure the pump is primed as described in the priming section before starting,
damage to the shaft seal will result otherwise. See Section 4 - Commissioning.

B. Water temperature

The water entering the pump must be controlled as follows:

1.13 The maximum allowable water temperature is 35 oC.

1.14 The minimum allowable water temperature is 4 oC.

C. Pipework - General

1.15 Secure pipework: Ensure pipework to and from pump is independently
supported & clipped to prevent forces being transferred to inlet and outlet
branches of pump.

1.16 Flux: Solder joints must be completed and flux residues removed prior to pump
installation (flux damage will void any warranty).

1.17 Pipework design: Care should be taken in the design of pipework runs to
minimize the risk of air locks e.g. use drawn bends rather than 90o bends.

1.18 DO NOT introduce solder flux to flexible hoses, pumps or pump parts
manufactured from plastic.

1.19 DO NOT allow contact with oil or cellulose based paints, paint thinners or
strippers, acid based descalents or aggressive cleaning agents.

1.20 DO NOT install a non-return valve, or devices which contain non-return
valves, in the suction (inlet) pipework to the pump. The pump must be
free to vent to the supply tank at all times. Exceptions can be made in
the case of suction lift installations when a footvalve is required.

1.21 DO NOT connect this pump to the mains water supply.

D. Plumbing Installation Regulations

1.22 The plumbing installation must comply with the current water and building
regulations.

1.23 The plumbing installation must be installed by a qualified person.

1.24 The electrical installation must be carried out in accordance with the current
national electrical regulations.

1.25 The electrical installation must be installed by a qualified person.

2 LOCATION - GENERAL

2.11 Access: For emergencies and maintenance the pump must be

easily accessible.

2.12 Protection: The pump must be located in a dry position, frost
free and protected from freezing, particularly when installed in a loft
(not recommended).

2.13 Ventilation: Ensure an adequate air flow to cool the pump. Separate
the pump from other appliances that generate heat. An 80 mm (3 “)

air gap must be maintained around the pump.

2.14 Safety: The motor casing can become very hot under normal

operating conditions. Care must be taken to ensure it cannot be

touched during operation.

2.15 Water retention: Site in a location where in the unlikely event of
a water leak, any spillage is contained or routed to avoid electrics

or areas sensitive to water damage.

2.16 Static inlet pressure: Before deciding where to locate the pump check to
ensure the static inlet head (Fig. 2) meets the minimum requirement of 1 metre
and does not exceed the maximum requirement of 5 metres.

2.17 Ambient temperature: The pump must be sited in a location where the
maximum ambient temperature does not exceed 40 oC.

2.18 Pipework: For optimum performance pipework 28 mm should be used.
22 mm is acceptable, however, any pipe size reduction will reduce the pumps
performance.

2.19 Do not run against a closed valve for periods longer than 5 minutes.

2.20 Portable: The pump is suitable for use as a portable unit and is provided with
a carrying handle for this purpose.

2.21 Pipe size: To prevent loss of pressure through pipework, use pipe size to match
pump (19 mm internal diameter) whenever possible, minimising 90° bends
(sweeping bends).

2.22 Isolating valves: If permanently installed, isolating valves MUST be fitted in
suction and delivery pipework to enable easy isolation and access to the pump.

2.23 Inline strainer: When pump is to be installed in areas where there is risk of
debris or scale build up within the system, you MUST ensure the inlet pipework
is fitted with an inline strainer.

2.25 Self Priming: Jet 55-45 and 80-45 pumps are capable of self priming the
suction hose assembly, providing a footvalve and strainer (not supplied) is
always used for this type of installation. The Jet pump can be used in a suction
lift installation providing the height of lift is no greater than maximum permitted
(Fig. 3).

2.26 Footvalve/strainer: It is important that the optional footvalve and strainer is
always used for suction lift installations. This pump is capable of a
maximum suction lift of 5 m in this case only, an NRV in the footvalve is
permissible (Fig. 3), Stuart Pt. No 26704.

2.27 Suction pipe: Lay the suction piping over the shortest possible distance and
ensure there is a constant rise from the water source to the pump. Any high
spots will cause air pockets to form reducing system efficiency. The suction
hose must be a minimum of 25 mm to ensure the pump is not starved of water
and must be reinforced to prevent it collapsing.

2.28 Connections: Ensure all joints in suction pipework are completely airtight.
Failure to comply will result in loss of prime.

2.29 Position: The intake of the footvalve/strainer should be positioned so that it
cannot be blocked with debris or silt that are frequently found in the bottom of
sumps and wells.
