Questions

FAQ

At Prime Fluid Management, we understand that every fluid management challenge brings unique considerations. Here, you’ll find clear, practical answers and expert guidance to help you maximise uptime, achieve regulatory compliance, extend equipment life, and implement the most effective solution for your site.

Do you supply oil transfer pumps that can meet API 676 requirements?

Some positive displacement internal gear pump ranges are manufactured to API 676, with specific exceptions depending on the model. If API 676 compliance is part of your specification, we can confirm suitability during selection and provide the relevant documentation.

What’s the best oil transfer pump in NZ for diesel, fuel oil, or lubricating oil?

The best option depends on viscosity, temperature, and whether you need steady metered flow or high throughput transfer. For many industrial oils and fuels, internal gear and external gear pumps are common choices because they provide consistent flow and handle higher viscosity fluids well.

Can these pumps be specified for hazardous areas?

Yes, hazardous area options may be available depending on the selected pump and motor package. For example, some equipment ranges offer certified IECEx hazardous area rated configurations, which can be specified when the site classification requires it – including suitable options for Zone 1 and Zone 2 hazardous areas.

Do you need flooded suction, or can the pump run on suction lift and self priming?

It depends on the fluid, temperature, viscosity, and how the tank and pipework are laid out. A flooded suction setup is usually the most stable option for consistent performance, especially with higher viscosity oils, because the pump is always supplied with product.

If the pump needs to draw from a lower level or from a longer suction line, suction lift and self priming capability become important. However, the setup needs to be sized correctly to avoid issues like poor priming, air ingress, or cavitation. If you share your suction conditions and duty point, we can recommend a pump type and configuration that suits the installation.

What features help protect the pump and improve reliability on fuel and oil duties?

For fuel and oil applications, reliability often comes down to protecting the pump from pressure spikes and contamination, and selecting the right sealing arrangement. Depending on the pump type and duty, options can include an internal relief or bypass valve to protect against dead heading, and an inline suction strainer to reduce the risk of damage from debris.

Seal selection also matters for demanding services, with configurations such as double mechanical seals used on certain duties where additional containment or reliability is required. We can guide you on what features make sense based on the product, operating conditions, and site requirements.

What information do you need to specify a fuel transfer pump in NZ?

To specify the right fuel transfer pump for a New Zealand site, we typically need the fuel type, required flow rate, temperature, and viscosity, along with suction conditions such as flooded suction or suction lift.

Once we have those details, we can confirm the most suitable pump type and configuration for your application – including options for heavier fuels where viscosity is higher.
