Red Lion RL20A 20-Gallon Pressure Tank
Designed for well pump systems, the RL20A helps maintain water pressure when the pump is off. It is NSF/ANSI/CAN 61 approved for safe drinking water and features a heavy-duty 20-gauge steel tank with a 304 stainless steel water connection and a leak-safe diaphragm system. The tank ships pre-charged at 20 PSI and requires topping off to the pressure switch cut-in setting minus 2 PSI with a bicycle pump.
Red Lion RL34A 34-Gallon Pressure Tank
With a larger 34-gallon capacity, the RL34A provides extended buffering for well systems, reducing pump cycling and stabilizing pressure during peak usage. It uses the same durable construction as the RL20A—20-gauge steel, 304 stainless water connections, and a billet diaphragm design. Pre-charged at 20 PSI, it also requires topping off to the appropriate cutoff setting.
Red Lion RL2A 2-Gallon Inline Tank
The RL2A is ideal for compact installations or small well systems where space is at a premium. Its inline design supports quick mounting and efficient pressure regulation with a 3/4-inch MNPT connection. It is pre-charged to 20 PSI and uses a similar leak-safe diaphragm and polypropylene liner as larger models.
160L/42.3Gal Stainless Pressure Tank
This stainless steel tank offers a larger capacity for residential wells and aggressive usage patterns. It features a robust 304 stainless construction, a three-arc base for stability, and a seal designed for leak resistance. It’s suitable for environments from -60°C to 60°C and aims to meet drinking-water standards. Note that it is a tank only; air control must be managed externally.
100L/26.4Gal Stainless Tank
A mid-sized stainless option, the 100-liter model emphasizes corrosion resistance and long service life. It shares a similar base design and automation concept with larger stainless options, supporting automatic pumping cycles while maintaining reliable water pressure in modest well systems.
Red Lion RL-SWJ50/RL6H Shallow Well Jet Pump Package
This all-in-one package combines a shallow-well jet pump with a pre-charged 5-gallon tank. It offers a compact solution for low-head wells, including a 30/50 pressure switch, gauge, and stainless steel hose, making it suitable for simple domestic wells with modest flow needs.
SEAFLO Accumulator Tank SFAT-075-125-01
SEAFLO’s bladder-style accumulator is designed to smooth water flow and reduce pump cycling in a variety of settings, including marine, RV, and off-grid systems. The unit maintains 125 PSI max pressure with a 0.75-liter bladder volume and a 1/2″ MNPT inlet/outlet, helping to extend pump life while delivering steady pressure to fixtures.
Buying Guide: Key Purchase Considerations For Bladder Pumps And Pressure Tanks
When selecting a bladder-style pressure tank or accumulator for a well, consider these factors to ensure optimal performance and longevity:
- Tank capacity vs. household needs: Larger tanks reduce pump cycling in high-demand periods, while smaller tanks save space and cost for modest uses.
- Pre-charge pressure compatibility: Match the factory pre-charge (commonly around 20 PSI) to your well’s cut-in pressure to minimize short cycling.
- Material durability: Steel tanks with stainless steel water connections offer long life and corrosion resistance; stainless options provide the best protection in harsh water chemistries.
- Bladder vs. diaphragm design: Bladder-based accumulators dampen flow pulses with a flexible bladder, while diaphragm designs manage pressure without a separate bladder in some models.
- NSF/ANSI safety certifications: Look for NSF/ANSI/CAN 61 compliance for drinking water safety if the system contacts potable water.
- Installation footprint: Inline tanks fit tight spaces; vertical tanks need upright clearance but often offer larger capacities per footprint.
- System integration: Ensure your pump, pressure switch, and gauge are compatible with the tank’s connections and set-up requirements (e.g., 1/2″ MNPT, 3/4″ MNPT, or 1″ FNPT).
- Maintenance needs: Some models include easy-access air charging points or simple diaphragm replacements; others may require professional service for gas-pressurized systems.
- Environmental conditions: Consider temperature tolerance and frost resistance where outdoor installations occur.
