PUMP NIRA 1 1/4 NIRA 9 1120

Nira 9 with nitrile seals is suitable for pumping diesel, oils, and water. The pump is also available with Viton seals, making it suitable for gasoline (product code 1122). The pump is mostly rust-resistant, but the oscillating shaft inside the pump may rust, which must be taken into account if the pump is to be used for pumping water. The pump is not recommended for drinking water, as it does not self-drain after use, leaving water inside the pump. Therefore, when used for water pumping, the pump must be emptied before freezing conditions set in, especially if located in areas at risk of freezing. The pump’s lift height is 4 meters without a foot valve, and 8 meters with a foot valve. When installing the pump, note that the suction pipe length affects the pump’s maximum suction height: a 10-meter horizontal suction pipe reduces suction height by approximately 1 meter. A 32 mm or 40 mm pipe is typically used as the suction pipe, with a foot valve installed at its end. Garden hose-type pipe is unsuitable as a suction pipe because it is too flexible and the pump’s suction will collapse it. This pump has an internal thread of 1 1/4"", but it is also available with a 1 1/2"" threaded outlet (product code 1121). The Nira 9 can withstand brief pressure of approximately 3 bar. The pump must not be installed in a system where it is continuously under pressure. When connecting the pump to a fuel tank, ensure the tank cannot empty itself (siphoning effect).
