Yamada Air Operated Double Diaphragm pump

Product catalog summary

Overview: The document is a product data sheet for Yamada Air Operated Double Diaphragm Pumps, specifically models NDP-5, NDP-10, and NDP-15. These pumps are designed for pumping a wide range of liquids, including volatile or inflammable ones, in hazardous areas. They are lightweight, compact, and can run dry, making them suitable for various industrial applications.

Performance and Specifications:

Performance Curves: Based on fresh water at ambient temperature. Performance varies with fluid properties.
Diaphragm Pumps: Self-priming from a dry start, robust construction minimizes maintenance.
Model NDP-5: 1/4” port, maximum capacity of 10 L/min, discharge volume per cycle of 20 cc, air pressure range of 0.2 – 0.5 MPa, maximum discharge pressure of 0.5 MPa, and maximum solid size less than 0.2 mm.
Model NDP-10 / DP-10: 3/8” port, maximum capacity of 20 L/min, discharge volume per cycle of 52 cc, air pressure range of 0.2 – 0.7 MPa, maximum discharge pressure of 0.7 MPa, and maximum solid size less than 1.0 mm.
Model NDP-15: 1/2” port, maximum capacity of 45 L/min, discharge volume per cycle of 70 cc, air pressure range of 0.2 – 0.7 MPa, maximum discharge pressure of 0.7 MPa, and maximum solid size less than 1.0 mm.

Materials of Construction:

Wetted Materials: Options include Polypropylene (PPG), Kynar® (PVDF), Aluminium (AC4C-T6), and Stainless Steel (SCS-14).
Diaphragm Materials: Options include PTFE, Neoprene Rubber (CR), Nitrile Rubber (NBR), Nordel® (EPDM), Santoprene® (TPO), and Hytrel® (TPEE).

Additional Notes: The material of the ball for Hytrel diaphragm pumps is Nitrile® rubber (NBR), and for Santoprene diaphragm pumps, it is Nordel® rubber (EPDM).
