Water Aspirator Jet 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.

Miniature Metering Diaphragm Pumps for Chemicals

With a footprint that's only a few inches in any direction, these diaphragm pumps fit into compact systems to dispense small amounts of acids, cleaning fluids, and other chemicals. They're often used in sterilization, photochemical, and water treatment systems. Choose from pumps with either a 4-20mA or 1-5V DC input signal that controls the flow rate.

Note: Pumps must be filled with liquid before use. They need a constant flow of liquid and cannot run dry.

Fixed-Flow-Rate Peristaltic Pumps for Chemicals

Also known as tubing pumps, these maintain a fixed flow rate. Pumps are self-priming, which means they create a suction force to draw liquid upward and fill the pump chamber. Mount them up to 25 feet above your liquid source. All can run dry. Do not use with solids.

Squeeze Bottles with Angled Nozzle for Harsh Chemicals


Fluorinated HDPE	FEP

Our most chemical-resistant squeeze bottles. These bottles are fluorinated to reduce permeability, absorption, and damage from harsh chemicals, such as ammonia and hydrochloric acid. Also known as wash bottles, they have a nozzle that dispenses liquid at an angle.

Fluorinated HDPE—Fluorinated HDPE bottles are an economical option that resists common solvents, such as ethanol. They’re ideal for routine dispensing and rinsing where contamination risk is low.

FEP—FEP bottles can handle the most aggressive solvents, such as acetone. They’re ideal for dispensing where you need high purity and minimal contamination.

Metering Diaphragm Pumps for Coolants and Oils

Use these diaphragm pumps for high-pressure output of antifreeze, hydraulic oil, and motor oil. They have an internal relief valve to prevent pressure buildup. The adjustment dial alters flow rate in 1% increments of the maximum flow. Pumps have a totally enclosed fan-cooled (TEFC) motor for use in dusty, dirty, and damp environments. Do not run dry or use with solids.

High-Flow Peristaltic Pumps for Chemicals

For high-volume chemical sampling and draining, these pumps have a powerful motor that enables them to move 2,592 gallons of liquid per day. They're commonly used with ammonia, acid-washing solutions, and cleaning fluids. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments. Pumps are self-priming and create a suction force to draw liquid upward. Mount up to 15 feet above your liquid source. They can run dry. Do not use with solids.
