The Essence of Pump Control Systems and Pump Controllers in Single and Multiple Pump Installations


Every day, pumps hum away in the background, playing an invaluable role in a staggering array of distinct applications. From fueling our vehicles at the petrol station to keeping crucial industries running, facilitating proper irrigation, and ensuring water supply systems function optimally, pumps are indispensable tools for transferring fluids in our modern world.

Yet, the implementation and efficient operation of these unsung heroes are not as straightforward as it may seem. It requires keen attention to intricate details and proper management tools to maintain optimal performance. The secret to their smooth operation is largely down to an unsung technological marvel: pump control systems and pump controllers.

Irrespective of the diversity in pump types and applications, controllers and control systems have become essential companions to these mechanical workhorses. They aid in the regulation and systematic control of pump operations, driving the seamless functionality of both single and multiple pump installations.

This insightful blog post aims to shed light on the intricate world of pump controllers and control systems. We will delve into their core functionalities, their versatility in managing single to multiple pumps across various fields, and how applicable Australian standards tie into this essential technology.

Whether you are a veteran in pump operations, a professional just getting your feet wet (pun intended), or someone interested in the technological aspects of our daily life – this post will offer understanding and appreciation for the refined sophistication of pump control systems and controllers in the world around us.

Join us as we navigate the fascinating narrative of pump control systems and pump controllers – the invisible keystones of our fluid-centric society.


Decoding Pump Control Systems and Pump Controllers


In the vibrant world of pumps, two primary components actively work behind the scenes to ensure effective and efficient functioning – the Pump Control Systems and Pump Controllers. Before we unlock the expansive realm of their functionalities, let’s understand their core definitions and the roles they play in pump operations.


Exploring the Types of Pump Control Systems, Their Applications, and Related Australian Standards


Pump control systems come in various types to fit the diverse range of applications, ensuring pumps perform optimally in distinct settings. As such, different pump control systems have been developed to handle the unique requirements of each instance. In this section, we’ll explore the variety of these systems, their various applications, and relevant Australian Standards that set the bar for performance and quality.

Constant Pressure Control Systems

Application: Typically employed in water supply and circulation systems, such as irrigation, domestic water supply, and HVAC. (Heating, Ventilation, and Air Conditioning)

Function: These control systems maintain a predetermined, constant pressure in the system by varying the pump speed according to the flow demand. The primary objective is to provide a stable fluid flow with minimal fluctuations in pressure.

Relevant Australian Standards:

  • AS/NZS 4020:2005 – Testing of products for use in contact with drinking water: This standard outlines the procedures for testing if a product affects the quality and safety of drinking water.
  • AS/NZS 3000:2018 – Electrical installations (Known as the Australian/New Zealand Wiring Rules): This benchmark for safe electrical installations also applies to the electric aspects of pump installations.

Level Control Systems

Application: Commonly found in wastewater treatment plants, tank filling and emptying systems, and stormwater management.

Function: Level control systems modulate pump operation based on fluid levels in tanks, reservoirs, or sumps. They initiate pump activation when the level reaches a predetermined height and cease operation once the desired level is attained.

Relevant Australian Standards:

  • AS 2417-2001 and AS 2417-2013 Rotodynamic pumps – Hydraulic performance acceptance tests: These set out requirements for the hydraulic performance of rotodynamic pumps and sets.
  • AS/NZS 3000:2018 – Electrical installations (Known as the Australian/New Zealand Wiring Rules): This standard ensures the safety of electrical installations associated with pump systems.

Alternating or Parallel Control Systems

Application: Used in multiple pump installations, such as water supply, industrial processes, and large-scale irrigation projects.

Function: These control systems manage the operation of multiple pumps by either alternating their usage (one pump running while the other is on standby), or running them in parallel to meet high demand. They effectively distribute workload, prolonging pump lifespan, and ensuring high operational efficiency.

Relevant Australian Standards:

  • AS/NZS 4020:2005 – Testing of products for use in contact with drinking water: This standard establishes procedures for testing the impact of materials on drinking water quality.
  • AS 2417-2001 and AS 2417-2013 Rotodynamic pumps – Hydraulic performance acceptance tests: These lay out the requirements for the hydraulic performance of rotodynamic pumps and sets.
  • AS/NZS 3000:2018 – Electrical installations (Known as the Australian/New Zealand Wiring Rules): This standard guides safe electrical installations for pump systems.

By adhering to the relevant Australian Standards, control systems ensure conformity to safety regulations, optimal performance, and top-tier product quality. Consequently, these sophisticated systems cater to the wide spectrum of pump applications, providing tailored fittings for unique scenarios that range from single to multiple pump installations.


Deep Dive: Types of Pump Controllers, Their Applications, and Relevant Australian Standards


Pump Controllers are the assistive compatriots of pump control systems. While control systems provide a macro-level operational command, pump controllers are the micro-managers, focusing on precise details affecting the options of speed, cycle, protection and diagnosis that are crucial for maintaining the efficiency and longevity of pumps.

Variable Frequency Drive (VFD) Controllers

Application – Often incorporated in constant pressure systems, HVAC, water supply systems, and systems where energy saving is a consideration.

Function – Adjust the speed of pumps based on the requirement. VFD Controllers effectively match pumps’ working pace with the demand, keeping the full control of pump capacity while consuming minimum energy.

Relevant Australian Standards

  • AS/NZS 3000:2018 – Electrical installations (Known as the Australian/New Zealand Wiring Rules): Provides guidelines ensuring the safety of electrical installations.
  • AS/NZS 3100:2009 – Approval and test specification – General requirements for electrical equipment: It forms a part of the procedures for the safety certification of electrical devices, including VFD controllers.

Pump Alternator Controllers

Application – Used in dual pump installations where the workload needs to be shared equally between two pumps.

Function – These controllers alternate the operation between two pumps, extending the lifespan and efficiency of each pump by ensuring equal wear and tear.

Relevant Australian Standards

  • AS/NZS 3000:2018 – Electrical installations
  • AS/NZS 3100:2009 – Approval and test specification

Pump Protection Controllers

Application – Applied across various pump systems to assure protection against potential pump-damaging conditions.

Function – These controllers are designed to protect pumps from conditions such as dry runs, cavitation, overheating, or deadheading, which can cause early pump failure.

Relevant Australian Standards

  • AS/NZS 3000:2018 – Electrical installations
  • AS/NZS 3100:2009 – Approval and test specification

Smart Pump Controllers

Application – Modern pump systems that necessitate real-time monitoring and troubleshooting.

Function – They offer system diagnostics, alerting system operators to potential issues with pump operation, enabling immediate action, or scheduling maintenance and thereby avoiding larger problems.

Relevant Australian Standards

  • AS/NZS 3000:2018 – Electrical installations
  • AS/NZS 3100:2009 – Approval and test specification
  • AS 4024.1:2014 – Safety of Machinery: Describes principles of safety for electrical equipment used in industrial machines.
