Multiquip 4682 Hand Pump Expanded

The Multiquip 4682 Hand Pump Expanded is a genuine OEM component designed for MVH408 and MVH508 series reversible plate compactors as well as HTN and HHN series ride-on power trowels. As a factory-sourced replacement, this part is produced to the same specification as the original unit installed during manufacturing, ensuring a correct, hassle-free installation. Confirmed fitment covers models including MVH408DE, MVH408GV, MVH408GH, MVH408DZ, MVH508GV, MVH508GH, HTN27K, HTN28K, HHN34TVD, HHN31V, and JWN24HTCSL/HSCSL, among others in the HTN and JTO series.

Key Features

• Genuine OEM Construction — Sourced directly from Multiquip, this hand pump is manufactured to the exact material and dimensional standards of the original, maintaining full hydraulic system integrity.
• Direct-Fit Replacement — Engineered to match the original mounting points and port connections, allowing straightforward installation without modification to fittings or lines.
• Broad Confirmed Fitment — Compatible with MVH408 and MVH508 reversible plate compactors and multiple HTN, HHN, and JWN ride-on power trowel models, making it a versatile stock item for mixed fleets.
• Consistent Hydraulic Output — A properly functioning hand pump delivers steady manual hydraulic pressure on demand; a worn or failed pump compromises blade pitch control on trowels and compaction performance on plates.
• Operational Safety on Hydraulic Systems — Correct pump function is critical to maintaining controlled hydraulic pressure; using an OEM-specified replacement helps prevent pressure irregularities that could affect machine control.

A hand pump is a manually operated hydraulic device that generates fluid pressure within a machine's hydraulic circuit without relying on the engine-driven pump. On reversible plate compactors such as the MVH408 and MVH508, it is used to build or release hydraulic pressure for directional control and operational adjustments. On ride-on power trowels like the HTN and HHN series, the hand pump assists with blade pitch or other hydraulic functions that require manual input. When the pump wears out or develops internal leakage, it loses the ability to maintain adequate pressure, resulting in sluggish or unresponsive hydraulic control that directly impacts machine productivity and operator safety.
