Import Tips
• Include stroke length and flow rate specifications to prove positive displacement reciprocating action
• Watch for reclassification if pump exceeds certain capacities better suited to rotary gear pumps
• Document end-use applications to distinguish from fuel injection pumps under automotive parts headings
