Specifications
• The performance curves below represent the measurements taken under the conditions prevailing at TACMINA’s test
facilities, and are provided here as examples.
• The individual conditions prevailing on-site and differences between models may produce minor variations from these
curves.
• Measure the discharge volume using the conditions under which the pump will actually be used, and set the stroke
speed in accordance with the applicable performance curve.
