Double Seal Plunger Pumps

Typical applications for double seal plunger pumps include methanol and corrosion inhibitor injection. Our pumps require either the TR-1 or TR-2 Timer/Relay in order to function. In the event that the pumps will be used within a SCADA system, a timer is not required.

Features

• The plunger is made of hardened 17-4 PH stainless steel. A protective coat of titanium nitride adds superior abrasion resistance and chemical compatibility for a longer service life.
• Hand tightened lock ring provides easy access to plunger and seal.
• The spring is made of Inconel and coated with Teflon for an extended service life.
• The plunger is separate from the air piston and can be replaced independently at one-third the cost of replacing both.
• Special cut-resistant ceramic check valve balls have a longer service life than standard stainless steel balls.

Specs

• All stainless steel construction.
• Double seal (DS).
• Wide selection of seal materials to ensure chemical compatibility.
