AISI 316L stainless steel, internal finish is n Ra 0.8. The DIN-FOOD centrifugal pump is built with a bare shaft or close-coupled construction with a shrouded motor, axial suction and radial discharge, connections with DIN-11864-2-B flanges. The impeller is of a half-open design with double curvature and manufactured in a single piece.

Each pump has performance limits. The pump was selected for certain pumping conditions at the time the order was placed. INOXPA shall not be liable for any damage resulting from the incompleteness of the information provided by the purchaser (nature of the fluid, rpm, etc.).
4. Installation 4.1. PUMP RECEPTION INOXPA cannot be held responsible for the damage sustained by the equipment during transport or unpacking. Visually check that the packaging is not damaged. The pump will be accompanied by the following documents: • Dispatch notes.
4.3. LOCATION Place the pump as close as possible to the suction tank, and if possible below the product level. Technical Place the pump so as to allow sufficient space around it to access the pump and the motor. (See Chapter 8 Specifications for dimensions and weight).
4.5. PIPES • As a general rule, the suction and delivery pipes should be fitted in straight sections, with the least possible number of bends and fittings, in order to minimise pressure loss caused by friction. • Ensure that pump inlet and outlet fittings are properly aligned with the piping and of a similar diameter to the pump connections.

• Connect the motor following the manufacturer’s instructions. • Check the direction of rotation (see the label on the pump). Start up the pump motor briefly. Make sure, by looking at the pump from the rear, that the motor fan is rotating in a clockwise direction. ALWAYS check the direction of rotation of motor with fluid inside de pump.
5.1. START-UP Technical Specification Read Chapter 8 thoroughly . INOXPA cannot be held responsible for the incorrect use of the equipment. NEVER touch the pump or the pipes when hot fluid is being pumped. 5.1.1. Checks before starting up the pump •...

7. Maintenance 7.1. GENERAL INFORMATION Like any other machine, this pump requires maintenance. The instructions contained in this manual cover the identification and replacement of spare parts. The instructions have been prepared for maintenance personnel and for those responsible for the supply of spare parts.
7.5. CLEANING The use of aggressive cleaning products such as caustic soda and nitric acid may cause burns to the skin. Use rubber gloves during the cleaning process. Always use protective goggles. 7.5.1. CIP process If the pump is installed in a system with a CIP process, it is not necessary to dismantle the pump. Assembly and Dismantling If there is no automatic cleaning process, dismantle the pump as indicated in the section.
7.6. DISASSEMBLY / ASSEMBLY OF THE PUMP 7.6.1. Pump and impeller body Disassembly Remove the hexagonal screws (52) and washers (53) fixing the housing (01) to the lantern (04).
