Diaphragm Pump Cast Iron 205-20-6661 Abrasive Water Jet Cutter Parts
Diaphragm Pump Cast Iron 205-20-6661 Abrasive Water Jet Cutter Part
The part 205-20-6661 is a diaphragm slurry-removal pump assembly in a cast-iron housing, engineered to evacuate spent abrasive and water (slurry) from the cutting tank of Waterjet systems.
Specifications
typical features of such assemblies include:
Housing Material: Cast iron for durability in abrasive environments
Pump Type: Double-diaphragm or single-diaphragm design, driven by hydraulic or pneumatic actuation
Connections: Inlet/outlet fittings sized to the machine’s tank plumbing (commonly 1″–2″ NPT or Flanged)
Seal Materials: Abrasion-resistant elastomers for diaphragm and check valves
Installation & Maintenance
Mounting: Secure the 205-20-6661 assembly to the machine frame near the tank outlet.
Plumbing: Connect inlet to the lowest point of the cutting tank and outlet to the abrasive separator or drain line.
Actuation Hookup: Tie into the machine’s pneumatic or hydraulic control circuit (as per OEM manual).
Routine Checks: Inspect diaphragms, check valves, and seals for wear every 500 operating hours; replace per service schedule.
Winterization: Drain and lubricate if operating in sub-freezing environments to prevent diaphragm stiffening.
