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: The performance data is based on fresh water at ambient temperature. The discharge volume and head can vary based on the fluid's properties.
Diaphragm Pumps: These pumps are self-priming from a dry start and have a robust construction that minimizes maintenance.
Model NDP-5: Maximum capacity of 10 L/min with a discharge volume per cycle of 20 cc. The air pressure range is 0.2-0.5 MPa, and the maximum discharge pressure is 0.5 MPa.
Model NDP-10 / DP-10: Maximum capacity of 20 L/min with a discharge volume per cycle of 52 cc. The air pressure range is 0.2-0.5 MPa for plastic pumps and 0.2-0.7 MPa for metal pumps.
Model NDP-15: Maximum capacity of 45 L/min with a discharge volume per cycle of 70 cc. The air pressure range is 0.2-0.5 MPa for plastic pumps and 0.2-0.7 MPa for metal pumps.

Materials of Construction:

Wetted Materials: 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 document includes notes on the materials used for the ball in diaphragm pumps, specifying Nitrile® rubber (NBR) for Hytrel diaphragm pumps and Nordel® rubber (EPDM) for Santoprene diaphragm pumps.

Contact Information: The head office is located at 2 Downgate Drive, Sheffield, S4 8BT, England. Contact details include a telephone number, fax, and email for sales inquiries.

FLOW Product Data Sheet Yamada Air Operated Double DIAPHRAGM PUMPS These pumps are lightweight, compact and easy to use for pumping a wide range of liquids. As they are air operated they are ideal for pumping volatile or inflammable liquids in hazardous areas. Self-priming from a dry start these pumps are ideal in situations where liquid has to be pulled from a container. The pumps can also run dry. The robust construction reduces maintenance to a minimum.

Discharge volume and head vary according to viscosity, specific gravity and other physical properties of the fluid/paste being pumped. To achieve the best diaphragm life and the most efficient air consumption, select a pump 1.5 times the required capacity.
