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.

Is an auto-prime pump the same as a “dry prime” or dry-prime dewatering pump?

On a lot of drawings and pump schedules, dry-prime pump or dry-prime dewatering pump is used as shorthand for a surface pump that can handle air and doesn’t need manual priming. In practice, the auto-prime units that Prime Fluid supplies are vacuum-assisted pumps with a dedicated priming system, so they meet the intent of most “dry prime” specs while giving you a modern, quieter and more efficient package.

When would I use auto-prime dewatering pumps instead of a self-priming dewatering pump or submersible?

Auto-prime units are usually the better option when the pump has to sit above the water, suction conditions might change, or you expect a lot of air to enter the line during setup and operation. A self-priming dewatering pump or submersible can still be the right choice on simpler, more static jobs, and Prime can talk you through which option will be more reliable and cost-effective for your site.

Do you supply diesel dewatering pumps and can they be automated?

Yes – Prime can supply auto-prime packages as diesel dewatering pump sets or electric sets, depending on what power you have available and how the system will run. With the right control panel and level sensors, those same units can be configured as an automated pump or “auto water pump” that starts and stops itself, which is helpful on remote or 24/7 sites where you don’t want someone constantly watching the pump.

Can Auto-prime Pumps be used for flood control and emergency response?

Auto-prime units are a good fit for temporary flood control pumps because they can be moved quickly, cope with long suction and discharge lines, and re-prime themselves as water levels change. Prime Fluid can set up high-flow Auto-prime Pump solutions for New Zealand councils and contractors that form part of a wider flood or stormwater contingency plan.

What information do you need to size the right Auto-Prime Pump in New Zealand?

To match an Auto-Prime Pump New Zealand job, one of our sales engineers will usually ask for your required flow, total dynamic head, suction depth, discharge route, expected solids size and how long the pump needs to run. If your documents mention terms like autoprime dewatering pumps, auto vacuum pump or use a generic “dry prime” note, sending those details through with a simple sketch of the setup helps the team recommend the most suitable package for your project.
