Warning Symbols

Throughout this manual the following symbols may be used where applicable

to denote any particular hazards or areas which should be given special

attention:

Note

This symbol highlights anything which would be of particular

interest to the reader or provides extra information outside of the

current topic.

Important

When this is shown there is potential to cause harm to the

device due to static discharge. The components should not be

handled without appropriate protection to prevent such a discharge

occurring.

Caution

This highlights areas where extra care is needed to ensure that

certain delicate components are not damaged.

Warning

DANGER OF INJURY TO SELF OR OTHERS

Where this symbol is present there is a serious risk of injury or

loss of life. Care should be taken to follow the instructions correctly

and also conduct a separate Risk Assessment prior to commencing

work.

1. Introduction

The SuperZip is a development from the Tritech International Ltd Zip Pump

and ZipJet range of products.

The integrated eductor based excavation system is designed to pump mud,

sand, gravel, drill cuttings and shale without the risk of blockage. A heavy

duty cylinder reverses the flow at the nozzle to eject any object which may

be causing and obstruction. A second cylinder operates a diverter valve to

provide a powerful direct jet to break up heavy and cohesive seabed mud and

sand prior to excavation.

Key features include:

• Separately compensated seal void to minimise ROV hydraulic oil

contamination

• Easy seal change and maintenance

• Lift handle and stabiliser foot

• Suction and jetting nozzles aligned

• Optional feed water filter

• Optional integrated suction and jetting nozzles

• Modular pump core to simplify maintenance

Warning

Never use the same size fitting for pressure hoses and the case drain. If

this is done there is significant risk of incorrect hook-up which will lead to

pressure being applied to the motor casing and could result in an explosion

and personal injury.

3. Installation

Warning

Do not power the pump or hydraulic valve actuators until all hoses

are properly connected to the pump.

There is a serious risk of injury to fingers if inserted into either the

power water intake or the pump delivery port.

If undertaking any testing operations suitable guards and other

safety measures must be in place.

3.1. Mounting

The pump may be mounted in any orientation on the vehicle. There are

four mounting holes each with 12mm diameter clearance. Two of these are

occupied by the stabiliser foot, which may either be removed or used itself as

a mounting. If desired a second stabiliser bar may be fitted in the alternative

hole set

The pump should not be mounted using the motor or hose nozzles as

attachment points.

3.2. Water Hoses

Hose Types

Note

The recommended hose type is the Kanaline AW/Hydrasun

Arizona

Kanaline AW hoses have plastic reinforcement and a semi-transparent wall

which assists in visual inspection for damage or blockages. Alternative makes

of suction and discharge hose may be used provided that they have a smooth

internal bore.

Any crush resistant PVC coil strengthened hose may be used if the

recommended hoses are not available.

Lay-flat style hoses are not recommended for discharge.

Fittings

Use standard Kanaline fittings or heavy-duty worm drive clips. Use of heavy-

duty two bolt clamps will result in damage to the hose connections on the

pump unit.

Clean Suction Intake Screen

It is recommended that a Tritech International Ltd supplied suction strainer

is used with the pump. If using another strainer it must meet the following

specifications:

• Maximum hole size: square mesh of 40mm aperture or circular perforations

of 60mm diameter.

• Minimum total free flow area: 0.016m²

The pump should not be operated in any circumstances without a suction

screen.

Dredge Suction Nozzle

Suction nozzles should be designed with a nozzle cross-section area of

approximately 40cm²

Smaller nozzles may be used but material removal rates will be reduced.

Larger nozzles are of no benefit and will reduce performance.

Installation SuperZip

A nozzle guard should be fitted that will pass a maximum of a 40mm diameter

sphere or 35mm sided cube. The pump can pass single objects of a larger

size, but if it takes in a stream of objects then blockages can occur.

Jet Nozzle

The recommended sizes are 14 to 19mm diameter or an equivalent area.

The optimum size will need to be determined by trial because the water

output from the power pump will vary depending on the oil pressure and flow

available from the ROV hydraulic system.

3.3. Hydraulics

Oil

The pump should be operated using a premium grade mineral based

hydraulic oil of ISO VG 22 to 32

Filtration

The hydraulic system filtration must be to a minimum of 10μm absolute

standard. A 10μm nominal standard is regarded as inadequate.

The recommended filtration is UN elements produced by Pall Industrial

Hydraulics Ltd. or equivalent products.
