OEM Titan Pump Component
Titan 806-032 Plunger (Replaces 551521) is an OEM precision-machined plunger that reciprocates within the pump cylinder to pressurize fluid on compatible airless sprayers. It provides a smooth, wear-resistant sealing surface for the packings. Not listed for RentSpray 650.
Compatibility Snapshot
Important: The 806-032 is not listed for the RentSpray 650. The RentSpray 650 uses a different fluid section assembly (704-554) and model-specific pump components. Consult the official parts diagram for your exact model.
Titan Pump Component Replacement
Titan 806-032 Plunger for Pump Pressure Generation Service
Titan 806-032 is an OEM precision-machined plunger that replaces Titan part number 551521. It is the reciprocating element within the pump cylinder that moves to pressurize fluid, providing a smooth, wear-resistant surface that seals against the pump packings. Over time, plungers can become scored, pitted, or worn due to contamination or normal wear, leading to pressure loss and fluid leakage. Replacing a worn plunger restores proper sealing and efficient pressure generation on compatible sprayers.
| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM precision-machined plunger for compatible Titan airless sprayers. Direct replacement for Titan 551521. The reciprocating element that pressurizes fluid in the pump cylinder. |
| Function | Reciprocates within the pump cylinder to pressurize fluid. Provides a smooth, wear-resistant sealing surface for the packings. Displaces fluid through the pump. Precise fit is critical for generating and maintaining high pressure. |
| Construction | Hardened and ground steel or ceramic for a smooth, wear-resistant surface. One source describes a tan-colored high-quality steel design. |
| Compatible Titan Machines | Advantage 400, Advantage 500, Impact 410. One source also lists EPX2155 and various i-series sprayers (440i, 640i, 840i). Always verify against your specific parts manual. |
| NOT Listed For | RentSpray 650. This plunger is not included in available compatibility data for the RentSpray 650. The RentSpray 650 uses a different fluid section assembly (704-554) and its internal pump components are model-specific and not interchangeable with other RentSpray models. The 806-032 is not referenced in the RentSpray 650 service documentation. |
| OEM Part Number | 806-032. Replaces 551521. |
| Related Parts Commonly Serviced Together | Plunger packings/seals (seal against plunger; always replace). Pump cylinder (check for scoring or wear). Connecting rod (drives the plunger; check for wear). |
| Common Problems Solved | Scoring or pitting on plunger surface; pressure loss (unable to build or maintain pressure); fluid leakage past packings; reduced output (lower than normal fluid delivery). |
| Target Users / Markets | Painting contractors, rental equipment operators, maintenance technicians, and repair shops servicing compatible Titan airless sprayers. |
| OEM & Brand Information | Genuine OEM component designed for correct fitment and reliable pump performance in compatible sprayer systems. |
