J-Class
The standard J-Class Tri-Seal 4-inch submersible pump features the Tri-Seal floating stage system. This stage system further improves efficiency and protects against wear when pumping abrasives (sand).
Tri-Seal
- 300 series stainless steel hub floats with the impeller maintaining a positive seal.
- Phenolic washer provides down-thrust protection.
- Acetal impeller provides high efficiency performance and abrasion resistance.
- Modified PPO diffuser and disc – proven abrasion resistant material.
- Floating stage design allows impeller to float independently.
- Removable, spring-loaded check valve.
- Maximum water temperature: 120 °F/ 49 °C.
- Ceramic shaft sleeve and rubber discharge bearing protect shaft and eliminate sand wear.
- Powered by Franklin Electric corrosion resistant 4-inch submersible motor with lightning protection.
- Patented impeller hub seal system seals radially and axially to prevent fluid recirculation, providing high performance in the harshest conditions.
High Capacity
- 4 performance ranges: 100, 150, 200 & 270 LPM.
- Stainless steel discharge head and motor bracket.
- High flow impellers and stages are glass-filled Noryl for maximum efficiency.
- Ceramic shaft sleeve and rubber discharge bearing eliminates sand wear.
- Intermediate bearing for increased shaft stability.
- Floating eye and hub seals improve performance and efficiency.
- Stainless steel hex pump shaft, shell and shaft coupling.
- High capacity upthrust assembly for protection during start-up and operation (150, 200 & 270 LPM models).
- Powered by Franklin Electric’s corrosion-resistant 4” submersible motor.
- 2” BSPP discharge threads.
- External check valve must be ordered separately.
