Monarch TT-20 & Franklin Electric FTT-20 Self Priming Trash Pump & Repair Parts
Monarch TT-20 & Franklin Electric FTT-20 Self Priming Trash Pump
The Monarch Industries TT-20, now widely recognized under the Franklin Electric FTT-20 designation, is the compact powerhouse of the TT Series. Designed for versatility and durability, this 2-inch frame-mount trash pump is engineered to withstand the rigors of industrial, commercial, and agricultural applications.
Constructed from heavy-duty cast gray iron, the TT-20/FTT-20 is built for environments where standard water pumps fail. It excels at transferring fluids containing solids, making it ideal for dewatering, marine bilge pumping, and liquid fertilizer transfer. With the ability to handle spherical solids up to 1 1/8 inches in diameter, this pump ensures consistent performance without the risk of frequent clogging.
Whether you are looking to replace a legacy Monarch unit or maintain your current equipment with genuine repair parts, this page provides the complete technical breakdown and component list for the Type A series.
Key Features and Engineering
- Robust Cast Iron Build: The casing is reinforced with extra ribs for added strength and vibration dampening, ensuring a long service life even in harsh conditions.
- Solids Handling Capability: The enclosed, two-vane cast gray iron impeller is specifically designed to pass spherical solids up to 1 1/8″ (1.125 inches), eliminating the need for a wear plate.
- Rapid Priming: Features a large capacity casing and a built-in NPT suction check valve. This prevents syphoning and allows for fast re-priming without a foot valve.
- Tool-Free Clean Out: The clean-out cover is secured by wing nuts, allowing operators to access the pump interior for inspection or debris removal without needing wrenches.
- Premium Components: Includes a stainless steel shaft with a keyway and a high-quality mechanical seal (Viton, stainless steel, and carbon-ceramic) for superior chemical and heat resistance.
- Double Ball Bearings: The shaft is supported by two heavy-duty sealed ball bearings to handle radial loads effectively.
Common Applications
- Agricultural: Liquid fertilizer transfer and irrigation.
- Construction: General dewatering and trench draining.
- Industrial: Sump drainage and waste water transfer.
- Marine: Bilge pumping and wash-down applications.
