MATTCO Wave Blockers eliminate up to 70% of the hydraulic resonance in discharge piping. Service histories show that systems experiencing hydraulic resonance can expect a substantial decrease in resonant response for each Wave Blocker installed in the piping down-stream from the discharge pump. All versions of the MATTCO Wave Blockers are designed and manufactured in the USA. Proper sizing and location are essential to Wave Blocker performance. Call us today for your specific application.
