Diaphragm Chemical Metering Pumps

Diaphragm Chemical Metering Pumps

Pump precise volumes of difficult to handle materials, such as fluids that are highly viscous or that contain fragile solids, with these diaphragm metering pumps. They are constructed of rugged materials to handle a wide range of chemicals, and have a diaphragm design that is sealless, self-priming, and can run dry without causing damage to the pump, all helping to reduce maintenance costs and downtime. They are a type of positive displacement pump, which are often used in applications where constant flow is required, and allows them to pump at medium to high pressures.

Outdoor Use

The assembly of these diaphragm metering pumps are designed to prevent outside water from entering the pump's feed stream, making them appropriate for outside use. They are also leak-free to contain the fluid being pumped and dampened to decrease noise.

Degassing

Allow for critical degassing of your chemical systems with these pumps with built-in vent valves. Commonly used for metering chemicals that tend to create gases such as sodium hypochlorite and sodium hydroxide, these pumps are able to vent gas with minimal return of fluid into the system. They release gas in a way that allows them to be self-priming and prevents them from losing their prime due to gas buildup, such as caused by the pump being run intermittently.

Heavy Duty

Constructed using durable materials designed to resist deterioration from most chemicals, these rugged diaphragm metering pumps are designed for continuous duty or high pressures such as in water treatment, ware washing, and pharmaceutical production. These pumps can generally maintain higher head pressures and baseline flow rates compared to other types of pumps.
