FLEXFLO® Peristaltic Chemical Feed Pumps by Blue-White

FLEXFLO® Peristaltic Chemical Feed Pumps by Blue-White

Blue-White’s FLEXFLO® Peristaltic Metering Pumps (Peristaltic Dosing Pumps) deliver precision fluid metering and accurate dispensing with a wide range of control capabilities. Peristaltic pumps have a gentle, nearly pulsation-free pumping action that makes them ideal for difficult-to-pump fluids such as gaseous chemicals, shear-sensitive fluids, viscous slurries and solids, and fluids with low moisture levels.

MD3 CHEM-FEED® Multi-Diaphragm Metering Pump

MD3 CHEM-FEED® Multi-Diaphragm Metering Pump

The MD3 Multi-Diaphragm Metering Pump delivers smooth, continuous chemical feed even when injecting chemicals that off-gas like Peracetic Acid and Sodium Hypochlorite. The cutting-edge Hyperdrive Technology allows for alternating pumping action between two diaphragms: when one diaphragm is in the suction phase, the other is in the discharge, resulting in a smooth chemical feed profile and eliminating the chance of vapor lock and loss of prime.

The MD3’s exclusive DiaFlex® Diaphragms will last the life of the pump, eliminating the need for expensive rebuild kits.

How to Choose the Correct Pump Technology for Your Application

How to Choose the Correct Pump Technology for Your Application

Specifying the proper chemical metering pump for an application can be difficult; however, the process will be simplified by acquiring all application parameters. It’s important to take into account such factors as the fluid to be pumped, the output volume required, and the pressure which the pump will be working against in the system.

Once all parameters are taken into consideration, the information will serve to guide the engineer or end user in selecting the best pump option to ensure optimal performance.

As compared to diaphragm style metering pumps, peristaltic units are the newer technology. However, in recent years peristaltic metering pumps have been widely accepted as the preferred technology in many applications, including: municipal drinking water and wastewater treatment; food and beverage processing; commercial swimming pool and aquatics water sanitation; as well as many others.

These types of applications use chemicals which off gas and calcify. When diaphragm pumps are used this can cause vapor locking as well as clogged valves. Peristaltic pumps are not affected by gas, air bubbles or particulates. Peristaltic technology allows the bubbles and particles to simply be moved through the system.

Also to be considered: peristaltic units do not require regular maintenance other than pump tube replacement due to wear. Diaphragm pumps, on the other hand, require ongoing maintenance as valves must be regularly cleaned.

The estimated life of the peristaltic pump tube can be determined when all application parameters are known. This allows operators to implement a regular maintenance schedule which can increase efficiency and prove to be cost-effective.
