Click on Your Pulsating Pump Type
Rotary Lobe Pumps Pulse Dampeners / Rotary PistonLobe Pumps (aka "rotary piston" - In German), popular for high viscosity ("non Newtonian") liquids, often need suction stabilizers, of the Flo-Thru type to ensure uninterrupted filling. Rotary Lobe Pumps have improved performance, use less power, and produce smooth flow when connected to pulsation-dampeners. Though relatively pulseless Tri and Bi Lobe Pumps show pulsation from the compression in the lobe root of the rotary pump. As rotary lobe pump use is often for high viscosity pulsation-dampeners with only one connection cause pressure pulses because of the energy required to force reciprocation up & down a "T" branch. All these recommendations are for "Flo-Thru."
Stop cavitation, save acceleration head losses, halve your pipe costs, increasing the safety, preventing pipe shake and fatigue, making your systems controllable, whilst ensuring instrument accuracy, increase pump life, and killing discharge pulses, concurrently preventing hydraulic shock and water hammer by: Providing instantaneous volume on demand with minimized pressure drop, removing the loss from re-acceleration of the whole supply line for every suction stroke, pipe size selection becoming for constant velocity instead of for peak velocity, intercepting high transient pressure spikes, reducing pressure changes which impinge on elbows to shake the pipe, neutralizing misleading readings, with protection against sudden sharp disturbances, smoothing pump head load changes that strain the drive train, dampening the rise and fall between pump discharge strokes, and softening the system into which a pump has to deliver gulps of volume. PulseGuard makes life easier safer and more economic all around. No system should be without a PulseGuard.
Know How to Connect it Before You Select it
This "Y,T" piece replaces the Ts that you would have to purchase and weld into your system. Its top face is an "O" ring flange. Dampers are serviced by simply removing the four bolts. If you wish to be able to run your system without the dampers in place we provide flow caps to go in place of the damper so that your system may continue to be used without the damper in place.
