Frequently Asked Questions

How do I choose the right pump?
Work out your required flow and your total head, including pipe friction and any filter or UV losses, then pick the model that meets that flow at that head — every Hydrostar MK4 flow on this page is quoted at 10 m head.
Can the Hydrostar MK4 be used on salt water?
Yes, with the optional seawater mechanical seal (SKU 63401625); the glass-reinforced thermoplastic body already resists corrosion and electrolysis.
Are these pumps self-priming?
Yes — all five models are self-priming, with a 6 litre strainer basket ahead of the impeller.
What power supply do they need?
All five Hydrostar MK4 models listed here are three phase; ask us to confirm the supply voltage and full load current for your site.
What pipe connections do they take?
The Hydrostar 200 has 65 mm connections and the 300 through 700 use 80 mm metric half unions.
What is the largest flow available?
The Hydrostar 700 delivers 1,500 LPM (90,000 LPH) at 10 m head from a 7.2 HP three phase motor.
How do I get a price?
Hydrostar MK4 pumps are quoted to order — send us your duty point, water type and supply details and we will come back with pricing and lead time.
