Stenner 85MJH2A2S Peristaltic Adjustable-Head Pump
The 85MJH2A2S is a variable-flow peristaltic pump designed for precise chemical dosing. Best for small to mid-sized residential pools where tight control of chlorine dosing is needed. It operates up to 100 PSI and supports adjustable flow from 0.8 to 17 GPD, using a Santoprene tube with 20 feet of 1/4″ tubing for robust chemical compatibility. This model is suited for buyers who want reliable automatic dosing with transparent head verification of flow. Caution: ensure compatibility with your chemical concentrate and verify tubing integrity periodically to prevent leaks.
Stenner 85MHP17 Chemical Metering Pump Kit
The 85MHP17 is a metering pump kit with adjustable flow from 0.8 to 17 GPD and 100 PSI, designed for chlorine-compatible applications. It includes Sanoprene #2 tubing and 20 feet of 1/4″ white tubing, providing clear, controllable dosing for precise chlorination. Best for installers who want a ready-to-assemble kit with visible flow confirmation. Limitation: line voltage is 220V/60Hz, which may require electrical planning or professional installation in some regions.
SeaSlep Off-Line Automatic Pool Chlorinator
This off-line chlorinator is a self-contained feeder with a 9-pound capacity that dissolves chlorine pellets independently of the pump system. Best for vacation-ready maintenance and for pools where in-line installation is impractical. It provides 360° adjustable control for tuning chlorine output. Caution: not all tablet types may be compatible; verify disk type before use.
Hayward CL100 Automatic Chlorine Feeder
The Hayward CL100 is an inline feeder designed for 3-inch trichlor tablets. Best for standard setups where inline dosing is preferred. Key feature is a dial control valve for adjustable feed rate and an Easy-Lok threaded cover for simple maintenance. Limitation: only as effective as system compatibility with your existing plumbing and pump configuration.
XtremepowerUS Automatic Chlorinator Feeder
XtremepowerUS offers an off-line chlorinator option suitable when inline installation is not possible. Best for installations requiring a stand-alone unit with easy installation and a 9-pound capacity for slow-dissolving 3″ chlorine tablets or bromine. It uses a dial-controlled feed mechanism. Caution: verify compatibility with your pool’s piping layout before purchase.
Buying Guide: How To Choose The Right Chlorine Pump Or Feeder
What pool size and use case should guide your choice? Inline feeders like the Hayward CL100 are straightforward for standard residential pools with existing equipment. Off-line feeders, like SeaSlep or XtremepowerUS models, suit spaces with limited plumbing or when you want a discrete installation. For precise chemical dosing and adjustable flow, peristaltic pumps from Stenner provide tight control, making them ideal for pools with variable usage or when you need accurate GPD settings.
Key considerations to compare across options include capacity and dispensing method, installation requirements, and tubings or discs compatibility. Peristaltic pumps rely on flexible tubing to transfer chemicals, which reduces contamination risk but requires tubing monitoring. Inline feeders rely on chlorine tablets or disks and can be easier for maintenance but must be compatible with your filtration system. Safety and electrical requirements should align with local codes, especially for high-PSI pumps or 220V equipment.
Summary of important buyer considerations:
- Pool size and usage: larger or high-traffic pools benefit from higher capacity and adjustable GPD.
- Installation constraints: inline vs off-line decisions depend on plumbing layout and space.
- Chemical compatibility: ensure tubing materials and tablet types are suitable for your chemical regimen.
- Control precision: seek models with clear flow verification and easily adjustable feed rates.
- Maintenance needs: consider ease of access to head, tubing replacement, and lid sealing.
FAQ
- What is the difference between inline and off-line chlorine feeders? Inline feeders connect directly to pool plumbing and dose chlorine as water passes through. Off-line feeders operate separately from the main line and add chlorine via a dedicated chamber or dosing cycle.
- Which pump is best for a small backyard pool? A compact peristaltic pump like the Stenner 85MJH2A2S provides precise dosing with adjustable GPD and is well-suited for smaller to medium pools.
- Can I use any chlorine tablets with these feeders? Tablet compatibility varies by model and tubing material. Verify tablet size and composition (e.g., trichlor) with the feeder’s compatibility specs.
- Do these devices require professional installation? Inline feeders often require basic plumbing and electrical connections; off-line options may be simpler to install for DIY users, but consult local codes if unsure.
- How often should I replace tubing in a peristaltic pump? Tubing life depends on chemical exposure and pumping frequency. Inspect for signs of wear and replace per manufacturer guidelines.
- Are these devices safe for saltwater pools? Many chlorine feeders are designed for standard chlorine chemistry; verify saltwater compatibility with the specific model and any required adjustments.
