Choose Your Small Mag-Drive Pump

Both models share the same compact dimensions, outlet size, and maintenance-friendly design. The difference is their flow capacity, power consumption, and maximum pumping height.

Model PB2545

Small Mag-Drive 290

290 GPH

A practical choice for smaller decorative fountains that need moderate circulation.

Power: 16 watts
Maximum head: 5.95 ft.
Current: 0.23 amps

Model PB2552

Small Mag-Drive 370

370 GPH

Choose this model when your fountain needs additional flow capacity or greater available lift.

Power: 24 watts
Maximum head: 7.6 ft.
Current: 0.40 amps

Important sizing advice: Maximum GPH is not the amount of water you will necessarily see at the fountain outlet. Flow decreases as water is lifted vertically and encounters resistance from tubing, fittings, and valves. Maximum head is the approximate shutoff height, not a recommended operating height.

Why Choose a Blue Thumb Mag-Drive Pump?

Compact Footprint

Designed to fit smaller fountain reservoirs and tight installation spaces without requiring a large pump housing.

Adjustable Water Flow

Fine-tune the fountain's water movement to help achieve the desired appearance and manage splash.

Serviceable Magnetic Drive

A magnetic-drive impeller with ceramic shaft supports dependable circulation and straightforward routine cleaning.

Protected Water Intake

The included foam pre-filter helps catch debris before it reaches the pump chamber. Regular cleaning helps maintain performance.

Plan for Separately

Compatible tubing and any application-specific fittings, fountain vessel, reservoir, decorative materials, and other plumbing or electrical installation components. These are not listed as included with this standalone pump.

How to Choose the Right Pump Size

1

Measure the Water Lift

Determine the vertical distance from the operating water level to the fountain discharge point. This is the starting point for estimating pumping head.

2

Account for Plumbing Resistance

Long tubing runs, narrow tubing, elbows, fittings, and flow restrictions reduce the water delivered at the outlet.

3

Select Your Desired Water Pattern

Consider whether your fountain needs a gentle bubbling effect or a more substantial water display. Select a pump with sufficient flow at the actual operating head.

4

Check Fit and Connections

Confirm reservoir clearance, a compatible 3/4-inch outlet connection, access for cleaning, and safe reach to a GFCI-protected outlet.

Installation and Everyday Care

Installing the Pump

Place the pump in a stable, clean location inside the fountain reservoir. Connect suitable tubing and position the outlet as needed. Keep the intake clear of gravel and loose debris.

Fully submerge the pump before operation and connect it to a properly installed, dry, GFCI-protected electrical outlet.

Routine Maintenance

Disconnect electrical power before handling the pump. Remove and rinse the foam pre-filter and inlet guard as debris accumulates.

If flow declines, inspect the impeller chamber for mineral deposits or obstructions and clean according to the owner's manual.

Important operating precautions: These pumps are for submerged operation only. Never run the pump dry, lift it by its cord, or service it while plugged in. Protect the pump from freezing conditions. Follow the official owner's manual for complete installation, electrical safety, and winter storage instructions.

Frequently Asked Questions

What is the difference between the 290 and 370 GPH models?

The PB2545 is rated for 290 GPH with 5.95 feet of maximum head and uses 16 watts. The PB2552 is rated for 370 GPH with 7.6 feet of maximum head and uses 24 watts. Both have the same housing dimensions, 3/4-inch outlet, and 16-foot power cord.

Can these pumps operate outside the water?

No. Blue Thumb specifies submerged-only operation for these Small Mag-Drive pumps. Maintain adequate water depth while operating and never run the pump dry.

Will the pump deliver 290 or 370 GPH at the top of my fountain?

Not necessarily. The listed flow is the maximum rating. Actual flow decreases as pumping height and plumbing resistance increase. Use the appropriate pump performance curve or ask Blue Thumb to help estimate delivered flow for your installation.

Can I adjust the water flow?

Yes. Both models include adjustable flow control so you can fine-tune the fountain's water movement within the pump's available operating capacity.

What size tubing connection do I need?

Both models have a 3/4-inch pump outlet. Confirm the connection type and compatibility of your tubing, adapters, and fountain fittings before ordering.

How often should I clean the pump?

Cleaning frequency depends on water quality and debris exposure. Inspect the foam pre-filter regularly and clean it whenever buildup restricts flow. If output declines after cleaning the filter, inspect and clean the impeller chamber following the manual.

Can I leave the pump outside during winter?

Do not allow water trapped in the pump to freeze. Before freezing conditions, unplug and remove the pump, drain it, and store it in a location protected from freezing. Follow the manufacturer's seasonal care instructions.

What warranty is included?

Blue Thumb lists a five-year limited warranty for the Small Mag-Drive pump family. Coverage is subject to the manufacturer's written terms and exclusions, including the impeller exclusion. Review the owner's manual and retain proof of purchase.
