Top Loading Arms Lined with PTFE

This specific configuration is intended for the transfer of highly corrosive chemical products and food-grade liquids, where resistance to aggressive media and compliance with strict hygiene standards are essential. The arms can be manufactured in carbon steel or AISI 316 stainless steel and are internally lined with PTFE (Teflon™) to provide excellent chemical resistance and prevent product contamination. The swivel joints, equipped with a single ball-bearing race, are also internally lined with PTFE and feature a double PTFE sealing system, ensuring enhanced durability, tightness, and long service life under demanding operating conditions.

Standard Configuration

• Right-hand layout, bottom inlet, ANSI 150 connecting flange.
• Base swivel T-20 style: It is used for horizontal handling It is provided with a ball-bearing race and is internally lined with PTFE with PTFE seals.
• Swivel Section: It is used to extend the range of action of the loading arm and is internally coated in PTFE.
• Double base swivel T-50 style: It is used for horizontal and vertical handling. It is made with two swivels, provided with a ball-bearing race, and is internally lined with PTFE with PTFE seals.
• Spring piston: It is used to balance the weight of the cantilever part of the loading arm
• Support tube: made of carbon steel or Aisi316, lined in PTFE.
• Safety butterfly valve: It is used to stop loading in the event of a malfunction during the supply. – Body and plate are made of stainless steel coated in PTFE.
• Terminal swivel T-40 style: It is used to hold the drop pipe upright; it can be equipped with a handle to make the movement of the arm easier.
• Drop pipe: it consists of a section made of steel or Aisi316, internally lined in PTFE, and a section in PTFE only which is put into the manhole it can be equipped with a splash guard disc or a cone made of Aisi316 or PTFE.
• Drip pan.
