If you are not sure if the hydraulic power

source being used to drive this pump is

properly sized or connected, call SPP

Pumps Limited.

The power unit should be located as near to

the pump location as possible. The

maximum length of hydraulic hose that may

be used without a significant reduction in

pump performance is 40m. However, by

increasing the hose diameter, performance

can be restored. Consult SPP Pumps for

more details.

The power unit is usually driven by a diesel

engine that may be mounted inside a noise-

reducing canopy for use in noise sensitive

areas to comply with local noise regulations.

The fuel tank should be sized to give

extended running time. The running time

will depend upon the pumping load.

The power unit should be provided with

automatic shutdown to prevent damage in

the event of low levels of engine or

hydraulic oil and high engine or hydraulic oil

temperature.

The speed of the engine should be

adjustable to suit the load on the pump,

reducing the speed for reduced demand will

increase fuel efficiency and reduce wear.

To minimise the potential harmful effects on

the environment in the event of an oil leak

or spillage, SPP Pumps recommend the

use of Biodegradable Hydraulic 46 Oil.

However, the pump will run satisfactorily on

good quality hydraulic oils of viscosity below

150SSU @ 38°C (100°F) or equivalent

specification.

NOTE – DO NOT MIX OILS

Note: When using vegetable (Rape Seed) based

biodegradable oil it is important to check

the condition of the oil frequently as it tends

to breakdown more quickly than the more

expensive mineral or synthetic

biodegradable oils.

To minimise wear and maintain pump

performance, the hydraulic oil must be

replaced regularly and the hydraulic circuit

must be fitted with a 10micron filter.

1.2 Hydraulic Hoses

The hydraulic hoses supplied for use with

this equipment are designed to prevent

incorrect connection, but if non-approved

hoses are fitted incorrectly, damage or

danger may result.

The hoses are supplied with quick release

couplings that must be correctly fitted

before starting the pump. Due to these self-

sealing couplings, the hoses will remain

filled with oil when not in use.

Damaged hoses should not be used, due to

the high pressure of the oil, a burst or leak

is hazardous, any damaged hose must be

replaced and returned to the supplier for

testing and repair before reuse.

1.3 Submersible Pumps

The S2TC-2 has a channel impeller with 2”

discharge. This pump is from a wide range

of submersible pumps to suit a variety of

pump applications.

For borehole applications use slim-line

pumps, for compact high volume

requirements use axial flow pumps, for

open water pumping use a conventional

pump with a vertical side discharge port.

To pump sewage or similar liquids with

solids or sludge content use pumps with

vortex impeller and for maximum

performance with clean water use pumps

with a channel impeller.

All pumps are driven by simple and reliable,

compact hydraulic motors and are fitted with

mechanical seals.

2. SAFETY PRECAUTIONS

2.1 Safety Symbols

Safety instructions within this manual are

marked with the following symbols:

This symbol refers to general

mechanical aspects of safety.

This symbol refers to electrical

safety.

This symbol gives warning of a

hazard to the pump itself, which in

turn could cause a risk to personal

safety.

2.2 Submersible Pump Safety Precautions

2.3.1

Ensure that the hydraulic power supply is

turned OFF and disconnect the hydraulic

hoses from the pump before working on the

pump.
