FAQ

Q1: How do I verify if this 7180-854U rotor fits my CAV DPA pump?
A: Please check the identification tag on your injection pump. The rotor number (853U) and specification (4/9R) must match the existing part. If you are unsure, please send us a photo of your old rotor or the pump data plate for verification.

Q2: What is the difference between a “Head Rotor” and a “Rotor” in a DPA pump?
A: The “Head Rotor” (often called the hydraulic head) is the complete assembly that includes the rotor, while the “Rotor” (number 853U) is the rotating element inside it. This product listing is for the complete head rotor assembly, which is the standard replacement unit for overhauling the pump’s distributor section.

Q3: What is the minimum order quantity (MOQ) and lead time?
A: The MOQ is 6 pieces. For stock items, we can ship within 24-48 hours after payment confirmation via TT, Western Union, or PayPal. For larger bulk orders, please contact us for a customized lead time and sea freight pricing.
