Multiquip EM994 Isolator

The Multiquip EM994 Isolator is a genuine OEM component designed for QP3TZ and QP2TZ trash pumps as well as vibratory screed equipment. As a direct OEM replacement, this isolator is manufactured to the same specifications as the original part, ensuring correct fitment and consistent performance across compatible Multiquip machines. Sourced directly through authorized channels, the EM994 is the correct choice when an exact replacement is required for these models.

Key Features

• Genuine OEM Vibration Control: — Engineered to the original damping and compression specification, this isolator delivers the same vibration attenuation as the part it replaces — critical for protecting both the operator and surrounding components from damaging vibration loads.
• Drop-In Fitment: — Matches the original mounting configuration on QP3TZ, QP2TZ, and compatible vibratory screed models, allowing straightforward installation without rework or adaptation.
• Broad Model Coverage: — Confirmed fitment across QP3TZ and QP2TZ Hatz diesel-powered trash pumps and the China-sourced vibratory screed line within the Multiquip portfolio.
• Protects Surrounding Components: — A correctly functioning isolator absorbs and disperses operating vibration before it transfers to the frame and engine mounts; a worn isolator allows excessive vibration that accelerates wear on fasteners, housings, and adjacent parts.
• Authorized OEM Part: — Sold by DHS Equipment as a genuine Multiquip part, carrying the part number EM994 exactly as cataloged, so you can verify fitment with confidence before ordering.

An isolator is a rubber or elastomeric mount that sits between two structural components — such as an engine or pump assembly and its frame — to absorb and dampen operational vibration. On trash pumps and vibratory screeds, the engine and vibrating components generate substantial cyclical forces during normal use; the isolator prevents those forces from transmitting directly into the machine frame, protecting the structure and reducing operator fatigue. When an isolator degrades, cracks, or collapses, vibration transfers freely through the frame, leading to accelerated wear on fasteners, housings, and connected parts, and noticeably rougher machine operation.
