❓ Frequently Asked Questions

Q: What is the difference between a circulation pump and a jet pump?
A: A circulation pump like the VP050 is designed for continuous, quiet operation to circulate water through the filter and heater 24 hours a day. Jet pumps are more powerful and are used to power the massage jets when you’re bathing.

Q: How quiet is this pump?
A: The VP050 operates at just 1400 RPM (half the speed of typical circulation pumps), making it significantly quieter than standard circulation pumps. It’s designed to run continuously without disturbing your peace.

Q: Will this pump fit my hot tub?
A: This pump uses 1.5-inch suction and discharge ports with 62mm thread outer diameter. Measure your existing pump’s port dimensions to confirm compatibility.

Q: What voltage does this pump require?
A: 230V / 50Hz single-phase supply, which is standard UK mains voltage. All electrical installation must be completed by a qualified electrician with proper RCD protection.

Q: How much electricity does this pump use?
A: The VP050 draws just 1.6A at 0.25 kW, making it very economical for 24-hour operation. Running costs are significantly lower than using a main jet pump for circulation.

Q: What cable connection does this pump use?
A: The pump comes with a 3-metre cable pre-fitted with an AMP plug connector, compatible with Balboa and similar control systems.

Q: Can I use this pump for jets?
A: No, this is a circulation pump with 0.33 HP – it doesn’t have enough power to drive massage jets. You need a dedicated jet pump (typically 1.5 HP or higher) for jet operation.

Q: Does this pump self-drain?
A: Yes, the centre suction design allows the pump to self-drain when switched off, which helps protect against frost damage in cold weather.
