Summary Purpose and scope of the manufacturer Features Modular Hydraulic characteristics of Literary Sources Online Resources As you might be interested in the following pages Summary fire pump NP 3000 is installed on the tanker fire. Produced by the German company Johstadt factorie and due to its characteristics in the classification of the Russian Federation would have marked PN-50/100. Purpose and scope Designed for water and aqueous foam in the seat of the fire. Installed on fire engines, mainly on the tanker. Manufacturer venture company Johstadt (Germany). Design features housing and impeller are made of seawater resistant aluminum alloy or alloy of copper and bronze. The pump shaft is made of stainless steel. The bearing assembly of the pump shaft and rubber polymer seal does not require lubrication for maintenance. Automatic evacuated system factorie VACUMAT + Piston vacuum pump does not require maintenance. Suction height 0 - 8 m. Modular system factorie A distinctive feature of almost all pumps for fire trucks production Johstadt, is a modular assembly factorie system that allows the customer to choose the complete set of the pump. Thus, a number of indicators of the pump when installed on the specific fire engines may vary. For example, the amount may vary, and the diameter of the suction and discharge ports.
