TECHNICAL INFORMATION

General description
The pump is designed and constructed to pump and compress liquids at high pressure in industrial applications.The pumping action is provided by a series of pistons connected to the drive shaft by connecting-rods.
When in operation,the pistons perform an axial stroke inside the head, where the intake and delivery ducts are fitted with valves that allow the liquid to pass in one direction only.

Main components

A). Head
B). Pump body
C). Crankshaft
D). Intake valve
E). Delivery valve
F). Guide
G). Seal
H). Piston

Intended uses
The pump is designed and built for incorporation in machinery and plants(machinery for washing raw materials,fnished products,etc.).
The pump must be used in a manner appropriate to its technical data(see"Technical Data"),and must not be modified or improperly used.

Misuses

Do not put the pump into service until the plant or machinery in which it is incorporated has been declared compliant with the relevant nationaland local legal requirements.
Do not use the pump in a potentially explosive atmosphere.
Do not use the pump for flammable,toxic or corrosive liquids,or those with unsuitable density.Do not take in liquids at temperatures higher than those specifed in the technical data.
Do not use the pump for the supply of drinking water.
Do not use the pump on products for human consumption.
Do not use the pump on pharmaceutical products.

Residual risks
Even if the safety regulations and information provided in the manual are complied with,the residual risk described below is still present during the use of the pump.
Thermal hazard: Depending on the temperature of the liquid pumped,the pump may reach high temperatures when in operation.The designer of the installation must therefore bear this in mind and provide the appropriate measures and warning signs for staff.

Technical Data

The technical and performance data are stated on the cover.

The pump's intake circuit must include a filter having a capacity at least twice the pump's delivery rate, which must not cause restrictions or head losses. The recommended degree of filtration is 50-80 mesh.Maximum intake vacuum-0.25 bar, measured at the pump intake.

NSTALLATION INSTRUCTIONS

Safety recommendations for installation

Take all possible precautions to allow the pump to be installed in a safe, risk-free manner.
All installation phases must be taken into consideration when designing the machinery or plant in which the pump is to be installed.
The design must consider all mounting points, the means of transmission of the energy sources, and the protective and safety devices required by the relevant regulations to prevent the risk of injury.

Installation

The mechanical connection between the pump and the motive power source may be made by means of a pulley and belt, or a flexible coupling, or through a direct flanged connection to the motive power source.
The crankshaft may turn in either direction.
The water supply connection can be made equally well to the intakes on the right or left of the pump(see diagram). Only connect the pump to filtered, clean water sources.
Unscrew the plugs fitted on the various ports in the factory by the manufacturer, and screw the plugs onto the ports not used, depending on connection requirements.
Replace the oil plug (A), used for shipment with the breather plug (B)supplied.

Mounting the pump
The pump must be installed on a horizontal surface with no flexible components between it and the mounting surface. The illustration shows the maximum permitted pump installation angle beyond which proper lubrication of the crank mechanism is not ensured. Secure the pump with screws of suitable diameter and length, fixing them through the holes provided in the pump body.

General guidelines on water supply connection
The pump's water supply connection can be made in one of the ways listed below.

Connection to the mains water supply.
Connection to a tank(gravity-feed).
Connection to an external pump(force-feed).

The following requirements must be met for all types of connection.

The pump must be supplied by means of a crush-proof hose of suitable diameter for the pump's intake connection(see "Technical Data").
There must be no restrictions or kinks in the hose.
A suitable filter must be installed at the pump intake(see "Technical Data").
All connections between the unions and the intake line must be sealed to prevent the pump from sucking in the air.
The connections and pipes must be suitable for the operating pressure and the pump delivery rate, and must comply with the relevant regulations.
To ensure operating safety install a relief valve(by-pass valve) suitable for the pump's technical data and with a suitable setting downstream of the pump.
The relief valve dump line must never be connected to the pump intake line.
Install a pressure damper downstream of the pump to minimise the water hammer effect in the delivery pipeline.

Connection to the mains water supply

The connection must comply with the recommendations provided.

The mains water system must have a flow rate twice the pump's rated delivery rate and a pressure of 2-3 bar.

When changing the oil, use an oil suitable for the conditions in the operating environment (see recommendations provided in the annexes and see"Environmental operating limits").
The correct lubricating oil viscosity depends on the external temperature.
Use the graph to select the degree of viscosity best suited to the temperatures of use.

Inspecting the pump mounting

Check that the pump's fixing screws have not become loose. If necessary, tighten them with the driving torque stated in the installation design.

Inspecting the connections and pipes

Inspect the connections for leaks.

Leaks can normally be dealt with by tightening the connections properly. If leaks from the intake pipeline connections are noticed, the seals must be repaired.

Inspect the hoses.

lf the pipes show signs of aging, breakage, swelling, rubbing, etc., they must be replaced.

Inspecting the Filter

If the flter cartridge is fouled or damaged, refer to the filter manufacturer's instructions for details on how to restore the filter cartridge to its original filtering condition.

Checking the oil level

Check the oil with the pump level and cold.
Check the amount of oil through the level gauge (A).
If necessary, top up with oil with the characteristics specified in the "Lubricants table".

To top up with oil proceed as described below.

Unscrew the plug(B) and pour oil in until it is halfway up the level gauge (A).
Screw on the plug (B).

Changing the oil

Position the machine in which the pump is incorporated perfectly level, with the pump slightly warm.
Do not release oilinto the environment.
Dispose of spent oilin accordance with statutory requirements.

To change the oil, proceed as described below.

Position a receptacle of suitable capacity to collect the spent oil.
Unscrew the drain plug (A)and allow all the oil to flow out.
Screw on the drain plug( A).
Unscrew the filler plug (B).
Pour in the fresh oil through the fller hole until the correct level is reached (see "Checking the oil level").
Screw on the fller plug( B).

Lengthy pump lay-offs

If the pump is to be unused fora long time, proceed as described below.

Run the pump with clean water for a few minutes.
Operate the pump without water for 10 seconds with the end of the delivery pipeline open to empty the pump and the delivery circuit and prevent scaling.
Flush the pump with water and solvents authorized by the relevant laws.
Dry the pump with a pressurized air jet.
Protect the pump from the weather.

Putting the pump back into service
Before putting the pump back into service after a long period out of use, check the oil level and the tightness of the mounting screws.
