Product Q&A

Q:Which mud pump models do your spare parts fit?

Our parts fit Chinese F/3NB series and mainstream Russian mud pumps: UNBT-600, UNBT-950, UNBT-1180L, UNB-600, 8T-310, 8T-650, UBT-400, BT-600, UB-590.

Q:What rubber material works best for seals exported to Russia?

HNBR is the top-tier material with superior durability. PU material is also widely adopted for moderate price and longer life. Cost-effective NBR rubber only fits neutral freshwater drilling scenarios.

Q:What is your minimum order quantity?

Small consumables like pistons and valve assemblies accept sample orders starting from 1 piece. There is no MOQ restriction for large structural spare parts.

Q:What is your complete payment process for orders?

T/T telegraphic transfer is our primary payment method: 30% deposit upfront, and 70% balance payment after you confirm the goods and packaging before shipment.

Q:What solutions are offered if received parts have size mismatch or quality defects?

Submit real photos and pump model information within 7 days after receiving goods. We provide free replacement, reshipment or partial refund once the issue is verified.
