  • Page 7: Introduction

    Acro-Smart Electronic Series January 2017 INTRODUCTION 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. The following instructions should be read and followed to correctly install and operate the pump and ensure optimum pump life and performance.
  • Page 8: Suction

    Acro-Smart Electronic Series January 2017 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.
  • Page 9: Discharge

    Acro-Smart Electronic Series January 2017 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 2500 Metering Pump, being a positive displacement pump, will be damaged if operated against a closed valve.
  • Page 10: Piping Arrangement

    Acro-Smart Electronic Series January 2017 Piping Arrangement WRONG CORRECT 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. 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.
  • Page 11: Operation

    Acro-Smart Electronic Series January 2017 OPERATION Before Starting 5.1.1 Ensure the pump will be operated within its specification. 5.1.2 Check gearbox oil level. Prior to leaving factory, each pump is filled to the correct level with the recommended grade of oil (see maintenance section).
  • Page 12: Capacity Adjustment

    Acro-Smart Electronic Series January 2017 CAPACITY ADJUSTMENT 4-20 mA Automatic Adjustment This pump is capable of accepting a 4-20 mA input signal to operate the capacity adjustment automatically. Ensure when connecting your 4-20 mA two (2) wire input signal are connected to Plug “D”...
  • Page 13 Acro-Smart Electronic Series January 2017 Manual Adjustment Standard manual capacity adjustment is by means of a key pad on the digital set point box mounted on the side of the electric motor. The manual capacity parameters for your pump have been pre-set and do not need any adjustment.
  • Page 14 Acro-Smart Electronic Series January 2017 CAUTION When power is turned off, or a power failure has occurred, the Blue LED lights on the key pad, will flash ON and OFF, when the power is restored. To restart the pump press the green start button to restore the preset default (L/Hr) setting and then adjust the manual capacity button to your...

    ETERING RETURNED FOR MAINTENANCE THAT HAS NOT BEEN SUITABLY CLEANED It is an Acromet Quality Assurance policy that all equipment returned for repair or service be supplied with a completed copy of the 'Equipment Decontamination Advice' form, as shown on page 37 of this manual.
  • Page 16: Diaphragm

    After the new diaphragm has been fitted, calibration should be checked and monitored until diaphragm has stabilised. All major mechanical repairs should be undertaken by Acromet's specialist servicing workshop in Melbourne. In most cases a pump can be repaired and despatched in one day.
