The problem

Espresso extraction pressure drifting means one cup strong, the next weak - bad reviews follow; sampling misses out-of-spec pumps and rework after assembly doubles cost.

Capability

Pump performance test bench for espresso and pump-type coffee machines, verifying pump pressure and stable extraction. Four stations with independent start; pressure 0.1-2.0MPa at 0.25 percent accuracy; flow 30-1000L/H; supply AC100-250V/50-60Hz from a built-in 3kVA AC source; 30L recirculating purified-water tank; 500W maximum per station; quick-clamp or pneumatic pressing couplers for pump inlet and outlet; automatic out-of-range alarm on discharge pressure, flow and pump power; electromagnetic flowmeters with back-pressure regulating valves; 10-inch touch screen with PLC and live data display.
