The video above discusses the working principle of Peristaltic Pumps

Sodium Hypochlorite is used in wastewater treatment to kill off bacteria before the treated water is discharged back into the environment. Also used in water treatment as a primary method of drinking water disinfection, Sodium Hypochlorite is quite a challenging product to pump. Hypo tends to “off-gas” and cause some metering pump types to vapor lock.

In the water treatment industry, and particularly when pumping sodium hypochlorite, traditional metering pump technologies suffer from vapor-lock when any significant volume of gas is encountered. With increasing preference toward liquid sodium hypochlorite versus chlorine gas, more and more wastewater and water treatment facilities require accurate and reliable metering pumps – which is why peristaltic pumps are the perfect pump choice for dosing sodium hypochlorite.

In a peristaltic metering pump, the fluid being dosed is kept totally enclosed within the tube. The tube is then compressed by a roller/rotor assembly, forcing the liquid inside along. Upon restitution of the tube, the resulting vacuum draws in more liquid. This process, known as peristalsis, is what makes the peristaltic pump the first choice for liquid metering. The tube is designed to provide millions of compression and restitution cycles. Because the pump uses no check valves, gas and vapor is not allowed to collect inside the pump. Rather, it is passed through to the discharge – no different than a liquid.

Let’s look at a unique peristaltic metering pump – the Verderflex Vantage 5000 from Verder (see the video below). The Vantage 5000 pump:

  • uses flexible tubing and a rotor/roller assembly to accurately convey water treatment chemicals across a 4,000:1 flow range at pressures from 0-100 psi;
  • has full SCADA interface with 7 selectable status outputs;
  • comes available with Profibus and Modbus protocols;
  • fully complies with the NSF/ANSI 61 Standard for Drinking Water System Components.
