Series 3000PR Plunger Pump

Precise metering begins with precise design

Choosing the right metering pump may seem like a straight forward

decision.....but in industry today there are often pumps that are either

under-specified, so the job is not being performed efficiently,

inadequate for the duty.....or over-specified. You need to be looking for

the right pump at the right price by making sure you are specifying the

right pump for the job. We supply Australia’s only manufactured range

of metering pumps to suit the right application to a remarkable range

of industries.

1. SAFETY

1.1 General

Please read and familiarise yourself with all sections of this and other equipment

manuals before proceeding with installation.

Observe all standard precautions which apply to moving machinery.

Observe all standard precautions which apply to electrical equipment, drives

and controls.

Pay particular attention to special safety 'cautions' and 'notes' in this

manual.

1.2 Mechanical Precautions

Prior to undertaking any mechanical maintenance repair, installation, etc.

SWITCH OFF, and disconnect the power before proceeding.

Personnel must wear the appropriate protective safety attire and remove

loose clothing, jewellery etc.

1.3 Electrical Precautions

Before undertaking work on the electrical controls or drives, disconnect

power and place a notice to advise others of the type of work in process.

Ensure all necessary grounds are in place and solid.

Do not disconnect or disable ground connections

CAUTION Follow all electrical regulations where required by electrical

engineering trades.

2. INTRODUCTION

2.1 Acromet metering pumps are designed and manufactured for long, low

maintenance service life and when properly applied, will give many years of

consistent accurate metering and trouble free operation.

2.2 The following instructions should be read and followed to correctly install and

operate the pump and ensure optimum pump life and performance.

2.3 The Pump specification sheet is enclosed at the end of this manual.

3. INSTALLATION

3.1 Location

3.1.1 It is desirable to locate the pump as close as possible to the supply source

(eg tank) in order to minimise suction losses.

3.1.2 The location should be dry and protected from rain and the possibility of

hosing down, with sufficient free space provided around the pump to

allow access for adjustment and maintenance.

3.1.3 The mounting surface should be even and level. The pump base is

provided with two (2) holes for mounting bolts.

4. PIPING

4.1 General

4.1.1 The pump suction valve is located at the bottom of the pump head and

the discharge valve on top. The pump cannot operate without these

valves and for correct operation, valves must be vertical.

4.1.2 Discharge pressure should be more than 20 kPa greater than suction

pressure to prevent over feeding or syphoning and to maintain metering

accuracy.

NOTE When the difference is less than 20 kPa, a back pressure valve and

pulsation dampener should be installed in the discharge line. The

pulsation dampener should be located between pump and valve,

as close to the pump as possible.

4.1.3 A characteristic of reciprocating pump performance is pulsating flow.

Piping should be sized for flow rates at least 3.5 times greater than

maximum capacity of pumps.

NOTE Small diameter piping will produce unpredictable flow rates and

system pressures.

4.1.4 Piping should be as short and straight as possible and arranged to avoid

loops or pockets where gas may accumulate.

4.1.5 All piping should be separately supported close to the pump to avoid

imposing pipe loads on the pump. When handling high or low

temperature liquids, measures should be taken to prevent distortion of

piping imposing loads on the pump.

4.1.6 All pipe work should be flushed clean of any solids which may be present

in the pipe work (i.e. weldslag, dirt following construction or repair)

before final connection to the pump and start-up.

4.2 Suction

4.2.1 Piping must be air tight.

4.2.2 For ease of maintenance an isolating valve should be located near the

pump inlet.

4.2.3 Solids should be prevented from entering low volume pumps or pumps

used for high accuracy metering. A strainer of 150-200 mesh is

recommended and should be adequately sized to prevent restriction of

flow.

4.2.4 Suction pipe entrance should be at least 75 mm above the bottom of

solution tank to allow settlement of larger solids in the tank.

4.3 Discharge

4.3.1 Should it be necessary to install an isolating valve in the discharge line, a

relief valve must be installed between the pump and isolating valve.

4.3.2 The 3000 Metering Pump, being a positive displacement pump, will be

damaged if operated against a closed or partially open isolating valve.

NOTE The relief valve should be set to operate at the maximum rated pump

discharge pressure or maximum rated system operating pressure,

whichever is lower.

CAUTION When pumping hazardous liquids the relief valve discharge should

be piped back to the supply source. This will avoid spillage should

relief valve operate.

NOTE To ensure correct operation and maximise valve life, a pulsation

dampener should be installed between valve and pump

4.3.3 A pressure gauge with gauge protector should be installed to check if the

pump is not operating at too great a discharge pressure. The gauge

should be provided with a petcock valve for isolation from the system

when not required.

4.3.3 When pumping into a high pressure system, a non return valve should be

installed as a safety precaution at the injection point.

4.4 Piping Arrangement Please note Plunger Pumps must have a flooded

suction to avoid damage by running the unit dry

Should it be necessary to

install an isolating valve in

the discharge line, a relief

valve must be installed in

the line between the pump

and isolating valve.

WRONG

CORRECT

Metering pumps are positive displacement pumps and produce pulsating flow. Consequently there

is considerable line pressure loss and suction piping should be sized to ensure adequate NPSHA. If

piping extends for a considerable distance a suitable break tank or pulsation dampener should be installed near

pump.

the pump.

Avoid pockets or loops in piping where gas may accumulate.

WRONG

CORRECT

Where the pump discharge line connects

with a high pressure line, install a

non return valve as a safety precaution.

The presence of solids in the pumped liquid can cause incorrect

pump valve operation and affect metering accuracy.

If solids are present install a strainer with 150 to 200 mesh

and large mesh surface in order to keep pressure drop as small

as possible and ensure that strainer does not become

quickly clogged.

CORRECT

NOTE The diagrams above are representational and are intended as a guide

only. For specific system design or advice please consult a pump systems

engineer or contact Acromet.
