The Square D brand Pumptrol 9013 pressure switch line hasbeen enhanced to be more corrosion-resistant and environmentally friendly,featuring RoHS-compliant Chromate 3 plating, which reduces the potential forcorrosion and rust. The new plating covers all metal parts, protecting theswitch’s key mechanical components. The diaphragm is manufactured to U.S Food& Drug Administration specification CFR 177.2600, making the switchescertified for potable (drinking) water systems, while meeting lead contentrestrictions for plumbing fixtures.
