1 Nira 6B
The Nira 6B is a high-quality hand pump with primarily rust-proof construction. The 6B is suitable for pumping
liquids such as water*, oil and glycol. Easy to maintain and offering a long service life, the 6B is ideal for
applications such as pumping water for sauna use and pumping oil from tanks. The Nira 6B is available also
with VITON seals for pumping liquids such as petroleum, and EPDM seals for pumping glycol. The Nira 6B
Arctic features ECO seals and is ideal for applications such as pumping fuels in sub-zero conditions.

2 Use
2.1 Before using
Before first using the pump please ensure that the packaging is intact and that there are no signs of damage
during transit. Any signs of damage should be reported to the delivery company and to the supplier within two
(2) days of receiving the goods. Ensure that all parts on the packing list are included in the delivery. Contact
the seller immediately if there are any problems with the delivery.
2.2 Installation
The pump is mounted to a vertical surface through the two holes in the pump body. The pump flanges have
either ¾” or 1” threads to which various kinds of suitable pipes or connectors can be fitted. Be sure to check
that all connections are tight.
2.3 Using the pump
The pump is ready for use as soon as it is installed. The pump can lift up to 4 metres without a bottom valve
fitted to the suction line, and up to 8 metres with a bottom valve. Without height differences the length of the
suction pipe can be tens of metres. Please note that the length of the suction pipe and the height difference
between the pump and the water source affect the pumping capacity.
If the pump is used for pumping water and there is a risk of freezing, make sure that the pump is emptied of
water thoroughly after use. If the pump is permanently attached to an oil container make sure that the container
cannot be unintentionally drained through the siphon effect. An accessory designed to prevent draining due
to the siphon effect is available for containers with a 2” internal thread from Nira’s online store (article P61808).
The same pump must not be used for pumping both water and oil
This product is not suitable for pumping drinking water or foodstuffs
Ensure that there is sufficient space around the pump for safe operation
Before using the pump make sure that nothing is in the way of the handle
Ensure that all the parts of the product are firmly fixed in place before use
Check the condition and operation of the pump regularly (at least once a year)
Do not use a defective or leaking pump
