6 Frequently asked questions
Q: Do Nira pumps freeze?
A: The Nira 6B must be completely emptied of water (or other liquids prone to freezing) before the
temperature descends below 0°C. To empty the pump, remove the suction pipe and operate the pump until
it is completely empty. Remember to also empty the suction pipe before winter. The durability of seals in
the winter depends on the seal material and the liquid being pumped.
Q: Do Nira pumps rust?
A: Hand pumps feature a steel mechanism which may rust over time. The Nira 6B is also available with all
parts in stainless steel.
Q: What liquids can be pumped with the Nira 6B hand pump?
A: Check the implementation chart. The aluminium-bodied Nira 6B is not suitable for pumping Ad Blue fuel
additive.
Q: From what depth can the 6B hand pump lift?
A: 4 metres without a bottom valve and 8 metres with a bottom valve fitted. 1 metre of lift corresponds to
around 10 metres of horizontal pumping (suction or pressure).
Q: Can the handle of the 6B pump be turned downwards?
A: This is not possible after purchase; a pump can, however, be ordered from the factory with the handle
downwards.
Q: Does the hand pump stop the siphon effect?
A: No. After pumping stops, if the end of the discharge pipe is lower than the level of liquid being pumped,
the liquid will continue to flow until the end of the suction line is no longer in the liquid (the siphon effect). An
optional accessory designed for containers with a 2” internal thread is available to stop the siphon effect.
