The Multiquip EM514040 Hydraulic Tank LS-S is a genuine OEM hydraulic reservoir designed for hydraulic-driven concrete pumps in the LS series, including the LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD. As a direct OEM replacement sourced through Multiquip's authorized parts program, the EM514040 meets the exact material and dimensional specifications of the original tank fitted to these machines at the factory. Correct fitment to these concrete pump models ensures the hydraulic system maintains proper fluid capacity, pressure integrity, and thermal management during continuous pumping operations. DHS Equipment stocks this part to help keep your LS series concrete pump running at full capacity.
Key Features
- OEM-Grade Construction — Built to the same material and weld specifications as the original tank, ensuring the reservoir holds rated hydraulic fluid volume without flex, seepage, or pressure loss under working conditions.
- Direct-Mount Replacement — Matches the original port locations, mounting bracket configuration, and fittings of the LS-S tank, allowing installation without modification to existing hydraulic lines or chassis mounts.
- Broad LS Series Compatibility — Confirmed fit for LS400, LS500, LS600, LS60TD, LS40D, LS40TD, and LS50TD hydraulic-driven concrete pump models.
- System Pressure Integrity — A properly sealed, correctly sized hydraulic tank is essential to maintaining consistent pump output pressure; a cracked, leaking, or undersized tank leads to cavitation, overheating, and loss of pumping force.
- Genuine OEM Part — Supplied as an authorized Multiquip OEM component, so you receive the exact part number EM514040 referenced in the LS series service documentation.
The hydraulic tank on an LS series concrete pump serves as the central reservoir for the hydraulic fluid that powers the pump's pistons, valve actuation, and hopper agitation system. It stores and conditions fluid between cycles, allowing heat to dissipate and air to separate before fluid is recirculated through the system. When the tank develops cracks, leaks, or loses structural integrity, hydraulic pressure becomes inconsistent, fluid temperatures rise sharply, and the pump's output volume and reliability deteriorate — making prompt replacement of a damaged tank critical to uninterrupted operation.
