Water Aspirator Pumps

Pick up chemical spills and remove liquids in vacuum filtering systems—these pumps create suction to draw up liquids and gases as water flows through them. They’re made of HDPE and polyethylene, so they won’t break down when exposed to highly corrosive chemicals and acids. The suction end has a barbed tube connector, which attaches to your vacuum tubing. The connector stays attached to your vacuum tubing and connects to the pump when you’re ready to use it again. These pumps also have an internal check valve to prevent backflow.

Supplied-Air Full-Face Respirators for Air Pumps

The portable pump on these respirators provides a continuous supply of clean air for one person.

Add extension hose (sold separately) to increase your span up to 300 ft. To maintain NIOSH approval, respirators must be used with the hoses listed.

Supplied-Air Hood Respirators for Air Pumps

When connected to an air pump, respirators provide a continuous supply of clean air. They have a chemical-resistant Tychem 2000 (formerly known as Tyvek QC) hood that protects against light liquid splashes. Tuck the hood with outer bib and inner bib into your clothing for splash protection.

Pinlock suspension hats adjust with interlocking straps. Ratchet suspensions adjust with an easy-turn knob.

Add extension hose (sold separately) to increase your span up to 300 ft. To maintain NIOSH approval, respirators must be used with the hoses listed.

Self-Contained Breathing Apparatuses

When working in confined spaces near hazardous chemicals, be prepared for an Immediately Dangerous to Life or Health (IDLH) atmosphere. Commonly stocked in labs, industrial facilities, or on gas lines, a worker can quickly strap on this apparatus for 30 minutes of breathable air. The full face mask forms a complete seal to prevent any contaminants from leaking in.

For fast access, hang on the wall using a mounting bracket (sold separately).

Mechanical Pump Shaft Seals with Extended Spring

Seal with Retainer and Straight Spring

For use in waste water, boiler feed, and compressor pumps, these seals have an extra-long spring that accommodates variations in seal cavity length. They come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket. Products cannot be sold outside North America due to restrictions.

Buna-N diaphragms and gaskets resist grease and a wide range of oils.

Carbon washers are for use with clean liquids.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

Narrow-Profile Mechanical Pump Shaft Seals with Extended Spring

With a smaller seal OD than standards seals, these seals have an extended spring that accommodates variations in seal cavity length. They're used in waste water, boiler feed, and compressor pumps. Seals come furnished as two pieces—the seal and the seat. The seal is comprised of the case, spring, diaphragm, and washer, which come locked together as one piece. The seat is comprised of the seat and the gasket. Products cannot be sold outside North America due to restrictions.
