The Multiquip EM50115 Lube Oil Tank Assembly ST80 is a genuine OEM component designed for the ST80 swing tube concrete pump. As a factory-sourced assembly, EM50115 matches the original specification exactly, ensuring it seats, it connects, and performs the way Multiquip intended. This assembly is the correct replacement for ST80 units requiring lube oil tank service or restoration, and is stocked and sold by DHS Equipment for fast fulfillment.
Key Features
- Genuine OEM Construction — Sourced directly from Multiquip, this assembly is manufactured to the same material and dimensional standards as the original unit installed at the factory — critical for a pressurized lubrication component where tolerances directly affect oil delivery.
- Direct Assembly Replacement — Supplied as a complete tank assembly, this part replaces the entire lube oil tank unit in one service step, restoring the lubrication circuit without the need to piece together individual components.
- ST80 Specific Fitment — Engineered specifically for the Multiquip ST80 swing tube concrete pump, this part is not a universal substitute — it is built to integrate with the ST80's lubrication system layout and mounting points.
- Lubrication System Integrity — A properly functioning lube oil tank keeps the pump's wear parts continuously coated and protected during operation. A cracked, leaking, or failed tank leads to accelerated wear on internal components and potential pump seizure.
- Complete Assembly for Efficient Service — Replacing the full assembly rather than attempting to repair individual tank components restores the lubrication system quickly and confidently, minimizing time off the pour.
The lube oil tank assembly on the ST80 concrete pump is a core part of the machine's lubrication circuit, responsible for storing and supplying oil to the pump's moving internal components — including the swing tube and wear plates — during pumping operations. Without a consistent supply of lubricant, these high-friction components wear rapidly, leading to reduced output efficiency and eventual mechanical failure. A damaged or deteriorated lube oil tank can cause oil loss, contamination of the pumped material, or a complete breakdown of lubrication flow, making timely replacement essential to keeping the pump operational and protecting the investment in the machine.
