Plaster Aggregate GRACO T-Max 506 17X980 for Trowel Pumps – replacement wear part

Plaster aggregate GRACO T-Max 506 model 17X980 for Trowel Pumps – replacement wear part is a component intended for compatible T-Max series plaster and mortar pumps. It functions as the aggregate/trowel element in the material feed path, exposed to continuous abrasive contact with plasters, mortars and render mixes. The part is supplied for maintenance and repair to restore original pump material flow characteristics and prolong operational lifetime in construction and rendering workflows.

Advantages

This replacement wear part is manufactured to match the geometry and fit of GRACO T-Max 506 series pumps, enabling straightforward installation and reliable sealing in the feed path. The component is designed for abrasion resistance to reduce wear rate when pumping gritty or high-finesse plaster and mortar blends. Using an original-design aggregate helps maintain consistent pump performance, reduce downtime and simplify maintenance procedures during repair or overhaul.

Suitable for

• Repair and maintenance of compatible T-Max series plaster and mortar pumps
• Replacement of worn aggregate/trowel components in rendering equipment
• Applications with abrasive plasters, mortar and cementitious render mixes
• Site service operations where restoring material flow and pump efficiency is required

Key specifications

• Function: aggregate/trowel element for material feed in T-Max plaster pumps
• Compatibility: designed for GRACO T-Max 506 series trowel pumps
• Material behavior: built for abrasion resistance in contact with plaster and mortar
• Purpose: replacement wear part for maintenance and repair to restore pump performance

How to use

Before installation, de-pressurize the pump and follow manufacturer safety procedures for maintenance. Remove the worn aggregate from the trowel pump according to the pump service manual, clean the mating surfaces and inspect adjacent components for wear. Fit the replacement aggregate ensuring correct orientation and secure any fasteners or seals as specified by the pump manufacturer. After assembly, run a brief test with compatible material to confirm correct feed rate and sealing before returning the pump to normal service.

Usage recommendations

Use the part as a direct replacement within compatible T-Max 506 pumps and follow regular inspection intervals for abrasive wear. When pumping highly abrasive or aggregate-rich mixes, check the aggregate and surrounding components more frequently and keep records of operating hours to plan preventative maintenance and avoid unexpected downtime.
