The Growing Importance of Energy-Efficient Industrial Pumps in New Zealand’s Commercial Sector

Electricity is expensive. 

And for commercial operations in New Zealand, industrial pumps are one of the bigger culprits behind high energy use. According to energy data shared by EECA New Zealand, these pumps account for roughly 12% of the country’s total industrial electricity consumption. 

That’s not a small slice of the pie.

This kind of usage leads to high operational costs and heavier environmental loads. With growing pressure to reduce emissions and become more efficient, businesses across the country are reassessing how they power and maintain their core equipment. In this case, Graco pumps and other efficient technologies are worth paying closer attention to.

Understanding New Zealand’s Industrial Pump Energy Use

How Much Energy Are We Talking About?

Many commercial operations rely on industrial pumps to move liquids such as water, chemicals, oil, food ingredients, you name it. While these systems work behind the scenes, their power consumption doesn’t go unnoticed. Even modest upgrades in energy efficiency can translate into significant savings for a facility that runs pumps around the clock.

EECA’s technical guidance on pump systems reveals that many pumps operate below optimal efficiency. Some systems are oversized. Others haven’t been maintained properly or haven’t been updated in decades. That means money leaks out just as fast as energy does.

The Value of Energy-Efficient Pump Systems

What Are the Practical Benefits?

Let’s get into why energy-efficient pumps are gaining traction across New Zealand industries:

• Lower Power Bills: Efficient pump systems use less electricity, cutting down on energy bills without affecting performance.
• Fewer Breakdowns: Newer pumps are designed with better components and updated controls, reducing wear and tear.
• Smaller Carbon Footprint: Efficiency upgrades reduce emissions, helping businesses align with the broader push for sustainability in NZ.
• Better Process Control: Modern pumps can be paired with smart sensors for real-time data and smarter system performance.

One standout example is a North Island food processing plant that replaced its outdated pumps with high-efficiency Graco pumps. They saw a 15% drop in energy use in just six months.

Graco Pumps: Smart Choice for NZ Businesses

What Makes Graco Pumps a Good Fit?

Graco pumps are widely used across commercial sectors, from food manufacturing to chemical manufacturing. Their reputation comes from reliable build quality, ease of maintenance, and consistent energy performance.

In New Zealand’s industrial settings, where equipment must perform well under pressure (literally), having a pump system that saves money while running efficiently is a smart investment. Some business owners prefer to switch gradually, replacing one unit at a time, while others invest in full upgrades after cost-benefit analyses.

Common features that make Graco pumps stand out include:

• Modular designs for quick servicing
• Low pulsation operation
• Durable motors with lower energy draw
• Flexible configurations for custom systems

For many commercial setups, these features mean reduced maintenance headaches and fewer unplanned shutdowns.

Aligning Pump Efficiency With NZ Sustainability Targets

New Zealand has set bold goals for emissions reduction, particularly in its industrial sectors. With energy use under constant review, pumps fall squarely in the crosshairs of efficiency upgrades.

The Government’s Emissions Reduction Plan and industrial decarbonisation strategies place strong emphasis on energy audits, equipment updates, and system redesigns. That’s where pump selection becomes more than just a backroom decision; it becomes a climate strategy.

Companies choosing more efficient technologies, such as Graco pumps, are making moves that align with New Zealand’s carbon goals. They’re also appealing to eco-conscious clients and future-proofing their business practices.

Support from EECA New Zealand

What Help Is Available?

EECA New Zealand actively supports commercial operators in making energy-efficient decisions. Through its business programs, EECA offers:

• Energy Audits: Site-specific assessments to identify where energy use can be improved
• Co-Funding: Financial support for qualifying energy efficiency upgrades
• Technical Support: Detailed resources for system improvements and best practices

One manufacturing facility in Christchurch received co-funding from EECA to overhaul its fluid-handling systems. The result? A 20% energy saving over 12 months and significant commercial energy savings helped offset the cost of the upgrade.

Breaking Down the Cost Equation

What Do Businesses Actually Save?

Every case will differ based on pump size, runtime, and product type. That said, businesses replacing inefficient systems report:

• Up to 30% lower energy bills within 12 months: This varies depending on the baseline system performance, but energy-efficient pumps, especially those designed with precision flow controls, can lead to immediate cost relief. In large commercial plants, this can amount to tens of thousands of dollars annually.
• Reduced maintenance visits: Energy-efficient pumps often run cooler and with less vibration, resulting in less mechanical wear. Fewer breakdowns mean lower technician call-outs and less unplanned downtime. Facilities save on both labour costs and replacement parts.
• Lowered cooling needs due to less waste heat: Older pumps often release excess heat into the work environment, forcing HVAC systems to work harder. Newer models operate with reduced friction and heat output. That reduces overall facility cooling demands, leading to secondary energy savings.
• Better operational planning: Predictable performance allows for more accurate scheduling of shifts and output. When pump systems run efficiently, businesses face fewer unexpected pauses, helping with output forecasting and reducing production delays.

All these gains help drive reduced operational costs, especially over a two- to five-year horizon. Maintenance, electricity, and downtime savings compound quickly. For some operators, investing in efficient pump systems has a return on investment (ROI) within 18–24 months.

Storage and Maintenance Still Matter

Even the best pump will fail if left unchecked. So, let’s not forget about proper upkeep. Here’s how smart facilities in New Zealand are extending pump life:

• Routine Inspections: Checking for fluid leaks, pressure irregularities, and noisy operation at regular intervals helps spot wear before it becomes a problem. Some sites perform weekly visual checks paired with monthly flow performance reviews.
• Seal and Bearing Checks: These are the most common failure points in many pumps. Technicians should inspect seals for cracks and swelling and bearings for noise or signs of overheating. Even a slight irregularity in these parts can drastically reduce pump efficiency.
• Motor Calibration: Ensuring the motor draws the correct amperage and runs at the intended speed avoids overloading circuits and prematurely wearing out electrical components. Calibrating motor settings also helps identify underperformance, letting staff address it before issues get worse.
• Pump Rotation for Stored Units: For pumps held in reserve, rotating the shafts every 30 days prevents flat spots from developing on bearings. It also redistributes internal lubrication and confirms the unit hasn’t seized or corroded while sitting idle.
• Climate-Controlled Storage: Storing pumps in areas with stable humidity and temperature levels avoids rust, moisture-related faults, and degradation of rubber seals. Desiccant packs, vapour corrosion inhibitors, or sealed plastic wraps can add protection in harsher environments.

All these habits combine to protect the pump’s performance and delay replacements. While upgrades are important, maintenance routines keep everything humming in the meantime.
