Q&A – Buyer-Focused Commercial Queries
Q1: Which machines does this part fit?
A: It is used on concrete pump trucks, boom pumps and trailer pumps. Confirm the machine model and the original part number before ordering, because mounting patterns differ between pump generations.
Q2: What are the main specifications?
A: material: Cast iron housing, hardened steel cylinder block & pistons, bronze valve plate; working range: Rated pressure 350 bar (peak 400–420 bar); displacement 28–260 cc/rev; speed ≤ 2,500 rpm; SAE / DIN mounting.
Q3: How long does it last?
A: Under normal concrete-pumping duty the expected service life is 8,000–12,000 h. Abrasive mixes, high pumping pressure and missed lubrication shorten it.
Q4: How do I confirm the right part?
A: Send the machine model, the original part number or a photo of the old part. We match it against the drawing and confirm before shipping.
