SAqr-ATEX

The Production Centre in Reus (Tarragona) has the saqr-ATEX certification that allows it to carry out repairs on non-electrical equipment with ATEX certification of any type and category: mechanical seals, cartridges, pumps, agitators, etc… Zone 0, 1, 2, 22, 24, etc, maintaining the same level of ATEX certification.

Certificación ATEX T4

Mechanical seals suitable for working on equipment installed in explosive atmospheres in categories 2 and 3 of group II (2 G/D) cT2 and group II 2 G Ex h IIB T4 Gbx, according to DIRECTIVE 2014/34/EU (ATEX) of the European Parliament and of the Council of 26 February 2014 on the harmonisation of the laws of the Member States concerning equipment and protective systems intended for use in potentially explosive atmospheres.

US federal agency responsible for ensuring the safety and wholesomeness of food and medicines. Through the Codes of Federal Regulations (CFR) it establishes a list of materials and chemical products approved for contact with food. Most common: 21 CFR 177.2600 applicable to rubber / 21 CFR 177.1550 applicable to perfluorocarbon resins.

This regulation determines the restrictions and requirements for materials in contact with food.

API Plan 23

Circulation of pumped fluids from the discharge to the seal flush connection, passing through a flow rate controller and a heat exchanger.

Plan API 31 Lidering

API Plan 31

Circulation of the pumped fluid from the pump discharge to the seal chamber, passing through a cyclone. Fluids with solids are returned to the suction area.

API Plan 51

Static column of non pressurised fluid inside a tank, through the quench connection.

API Plan 52

Forced circulation of an external non-pressurised fluid used as a barrier fluid.
This fluid is circulated through a pumping ring due to the thermo-siphon effect.

Plan API 53A

API 53A Plan

Forced circulation through a pumping ring of a barrier fluid in a pressurised tank with a pressure that is 2 bar higher than the product fluid.

API Plan 62

Injection of an external fluid to be used for quenching and flushing/washing. The quench lubricates the seal contact surfaces on the air side, with vapour or water. The flushing/washing operation has a lubricating function.
