The AMT Pump 055-338 high pressure hose kit consists of a 20' PVC suction hose with a 2" diameter, a 100' PVC discharge hose with a 2" diameter, a 1-1/2" fire nozzle, a 1-1/2" to 2" adapter, and a hose wrench, and is suitable for use with a compatible high-flow drainage pump for firefighting, industrial wash-down, and general dewatering applications. The PVC (polyvinyl chloride) construction of both hoses provides resistance to alkalis, weak acids, and abrasion, and the rigid PVC helix reinforcement of the suction hose provides the strength necessary for its full vacuum rating. The suction hose has a maximum pressure rating of 65 pounds per square inch (psi) and the discharge hose is rated at 100 psi. These hose assemblies can withstand temperatures ranging from 10 to 150 degrees F, and each one comes equipped with a 2" aluminum male National Pipe Straight Hose (NPSH) coupling and a brass female NPSH coupling. Female NPSH couplings are compatible with male National Pipe Thread Taper (NPT) connections. This hose assembly kit is suitable for a wide range of industrial, commercial, and residential firefighting, wash-down, and dewatering applications in conjunction with a compatible pump.Industrial hoses and hose assemblies transfer or convey air or liquid in hose systems. When selecting industrial hoses or hose assemblies, use the STAMPED method to help determine the type of hose needed:S= Size (ID, OD, and length)T= Temperature (maximum and minimum temperatures of material being transported)A= Application (industry or process)M= Material (to be conveyed, type and concentration)P= Pressure (maximum working pressure)E= Ends (type of end connectors or couplings on hose)D= Delivery method (volume and velocity)The inside diameter of the hose must be adequate to keep pressure loss to a minimum and avoid damage to the hose due to heat generation or e
