    Specification

    Choosing the right product

    Factors to consider when selecting a vacuum pump, from application needs to environmental conditions:

    • Desired vacuum level
    • Flow rate or evacuation time and vessel size
    • What is being degassed, process, moisture, temperature, corrosion
    Choosing the right product
    Lifetime Economy

    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. 

    What do drainage submersible pumps do on site?

    Drainage submersible pumps remove or transfer unwanted water from a wide range of environments — from construction and mining sites to tunnels, basements, and flood zones. Designed to operate fully submerged, they eliminate the need for priming and reduce the risk of cavitation. Their ability to handle water with suspended solids ensures reliable performance in demanding conditions.
    Can these pumps run dry?

    Yes — selected Grindex models feature advanced run-dry capability, with built-in thermal protection and a modular design that simplifies maintenance. This not only protects the pump during unexpected dry runs but also contributes to their reputation as one of the most reliable and durable drainage submersibles on the market - ideal for long-term, low-maintenance performance in demanding environments.
    What size and performance range do you cover?

    Across the ranges shown, inlets span roughly 2–10 inches with max flows listed up to about 350 L/s and heads up to 200 m on certain models. Check the overview tables or download the Dewatering, Bypass & Sewage Pumps Guide to match size, head, flow and solids to your job. 
    Do you supply and support submersibles NZ-wide?

    Yes. Prime Fluid Management operates across New Zealand with six branches, a warehouse and servicing workshop. We provide equipment, service and support nationwide. 
    What’s the difference between drainage and sewage submersibles?

    Drainage units focus on dewatering clean to lightly contaminated water and managing site water levels. Sewage units are engineered to move raw or solids-laden wastewater, with cutter, vortex or single-channel impellers to reduce clogging and pass larger solids.
