►NDP-15

 

Read below to learn more about Yamada’s NDP-15 port dimensions. 

 

Intake & discharge connection: 

Polypropylene (PPG)*            1/2″ Female NPT 

Kynar (PVDF)**                      1/2″ Female NPT 

Groundable Acetal**              1/2″ Female NPT 

Aluminum (ADC-12)***           1/2″ Female NPT 

Stainless Steel (316)***          1/2″ Female NPT 

 

**Kynar and Acetal pumps are fitted with flat check valves only. 

***Aluminum and Stainless Steel pumps are fitted with ball check valves only. 

 

Flow and Head Capability: 1 – 15 GPM / up to 231′ TDH
Polypropylene pumps may be fitted with ball or flat check valves. Ball-type check valves are recommended for flooded suction applications. Flat-type check valves are recommended for suction lift applications.  

 

Air inlet: 1/4″ Female NPT (includes ball valve) 

 

Air exhaust: 3/8″ Female NPT (internal silencer) 

 

Maximum Liquid Temperature*

Diaphragm Material / Temperature: 

  • Neoprene:                       180°F (82°C)
     
  • Buna N:                           180°F (82°C)
     
  • Hytrel:                              248°F (120°C)
     
  • Santoprene:                     225°F (107°C)
     
  • Viton:                               248°F (120°C)
     
  • Teflon: (PTFE)                 212°F (100°C)
     

* Polypropylene and Acetal pumps have a maximum liquid temperature of 180°F (82°C) regardless of diaphragm material. Kynar pumps have a maximum temperature of 248°F (120°C) when fitted with Hytrel or Viton diaphragms. 

 

Air Supply Pressure (All Models): 20 to 100 PSI (1.4 to 7 kfg/cm) 

 

Discharge Volume Per Cycle: Flat-type check valve-0.0375 gallons (138 cc) 

 

Ball-type check valve: 0.031 gallons (119 cc) – 

  • Maximum Cycles Per Minute- All diaphragms: 400
     
  • Maximum Size Solid- 1/32″ (1 mm)
     
  • Maximum Dry Suction Lift- Flat-type check valve: 8-feet Ball-type check valve: 5-feet
     
  • Pump Air Motor- Ryton air motor standard 

 

Notes: Hytrel-fitted pumps include Buna N check balls & wetted o-rings. Santoprene-fitted pumps include EPDM check balls & wetted o-rings.
