The Multiquip EM25435 Block Manifold 3 x 4 1 is a genuine OEM component designed for ST30 and ST80 swing tube concrete pumps. Sourced directly from Multiquip, this manifold block meets the same specifications as the original part installed at the factory. Confirmed fitment covers the ST30 and ST80 series, making it a straightforward like-for-like swap for operators keeping their concrete pump in working order. DHS Equipment supplies this as an authorized Multiquip OEM replacement, so you can order with confidence knowing you are receiving the correct part.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the manifold passages and port dimensions match the hydraulic and material flow specifications of the pump circuit.
- Direct Swap Installation — Bolt pattern and port configuration match the original mounting points on ST30 and ST80 concrete pumps, allowing the manifold to seat and seal correctly without reworking surrounding plumbing.
- Confirmed ST30 and ST80 Fitment — Verified compatibility with Multiquip ST30 and ST80 swing tube concrete pump models, eliminating guesswork when sourcing this manifold block.
- Maintains Consistent Material Flow — A properly functioning manifold block ensures concrete is directed through the pump circuit without pressure loss or cross-flow, sustaining output consistency on the pour.
- Hydraulic Circuit Integrity — A worn or cracked manifold block can cause internal leakage, pressure drop, and erratic pump cycling; replacing it with a genuine OEM part restores circuit integrity and protects downstream components.
The manifold block on a concrete pump is a ported distribution component that routes hydraulic or material flow between multiple circuit branches within a compact, unified housing. On swing tube pumps such as the ST30 and ST80, it plays a central role in directing the hydraulic signals that control the swing tube movement and piston sequencing. When the manifold block cracks, erodes, or develops internal bypass paths, pump timing and output pressure become unpredictable, which can interrupt pours and cause premature wear on pistons and the swing tube itself.
