Dixon/JEC RZL 100 Series rotary lobe pumps in 316 stainless steel construction and multi-lobe rotors, distributed by Kaman Industrial Technologies, provide minimal pulsation and high-accuracy dosing for fluids with low and high viscosities. Flow rates range from 0.53 to 5.54 gallons per 100 revolutions with connection sizes ranging from 1 to 2 inches using standard clamp connections, allowing for pressures of up to 300 psi. The front-loading tungsten carbide single mechanical seal is suited for a variety of chemical applications and is easily maintained without having to remove the pump from the process line. The line can be automated with a variable-frequency drive for applications that require dosing at different rates within the same process with the same accuracy. 800/526-2626; www.kamandirect.com.
