PUMP NIRA 1 1/2 NIRA 9 1121

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. The pump is mostly rust-resistant, but the oscillating shaft inside the pump may rust, which must be considered if the pump is to be used for water pumping. 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 arrive if it is located in an area 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 soft and the pump's suction collapses it. In this pump, the internal thread of the couplings is 1 1/2", but the pump is also available with a 1 1/4" threaded coupling (product code 1120). Nira 9 can withstand brief pressure up to 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). This product description is an automated translation of the original Finnish description.
