P
PTO-Engagement Indicator
Indicator light confirming the power take-off is engaged. Prevents accidental driving off with the PTO still active.
Pulsation Dampener
Reduces flow ripple in diaphragm pumps.
Pressure Test Point
Dedicated port for attaching pressure gauge.
Pulseless Gear Pump
Precision gear pump delivering steady binder flow at low rates.
Pressure-Gauge Calibration Adaptor
Adaptor allowing in-situ calibration of pressure gauges. Used by engineers during annual verification checks.
Pump Drive Coupling
Flexible coupling connecting PTO output to hydraulic pump input. Absorbs minor misalignment and torsional vibration.
Pressure-Gauge Panel
Panel grouping multiple system-pressure gauges in one location. Allows engineers to monitor suction hydraulic and water pressures at a glance.
Pressure-Relief Manifold
Manifold grouping several pressure-relief valves in one block. Simplifies plumbing and centralises safety functions.
Pick-Up-Head Lifting Ram
Hydraulic ram raising or lowering the suction head. Controlled from the cab for instant clearance over speed bumps.
Pre-Shift Safety Brief
Short briefing held before multi-vehicle operations. Ensures all crew understand route plans hazards and communication signals.
