Description
3” polypropylene pump, impeller and wear plate. Mounts to standard 3/4” keyway “Q” shaft engines, bearing pedestals, hydraulic pedestals or our Baldor motors. Features include:
- Viton elastomer seal with stainless spring & carbon/ceramic seal faces
- Up to 240GPM
- Max 12’ suction lift. A foot valve is recommended to help keep prime
- Internally bypassing at roughly 40PSI so it won’t blow a hose apart
- Priming plug to purge all air from pump bowl to ensure seal longevity
- Drain plug for easy winterization
- Self-priming with suction flapper to maintain pump prime in most installations
- 3-year warranty on Honda engines. More info available under Warranty tab
- 1-year warranty on Baldor motors. More info available under Warranty tab
- 1-year warranty on pump defects. Leaking seal, or damage due to misuse is not covered under warranty.
Cautions:
- Not for pumping gasoline, diesel, kerosene, aviation fuels, or any other combustible or flammable liquid. For pumps suitable for refueling, please see our fuel pump section of the website.
- Do not run pump dry. Wet seal pumps available under our DWS line.
- Pump suction must be the same size or larger than the discharge! If discharging 1-1/2”, you must use 1-1/2” or 2” suction. Failure to follow proper pipe sizing will result in cavitation, which will lead to pump failure and is not covered under warranty.
- Minimum GX-200 or 6.5HP electric motor!
Plumbing tips:
- To maximize your pump’s capability, use as few 90° elbows as possible. This is especially important on the suction side of the pump.
- These self-priming pumps are designed to provide high flow, but they like to push water, rather than pull it. You can maximize your pump’s performance by keeping the suction line as short, and as straight, as possible.
- 90° elbows are unavoidable. However, we highly suggest using long sweep elbows instead of hard 90° elbows.
- Here’s an example of how badly 90° elbows can affect your flow. In 3” line, every 90° elbow is equivalent to adding an extra 11’ of line. A sweep elbow, however, adds about 8’. A 45° elbow adds 4’ of line. So, if you add 5 90° elbows, you’ve added 55’ to the suction line. By adding that many elbows, you drastically reduce the pump’s efficiency.
- If you have to have numerous elbows, it is recommended you increase your suction line by one pipe size (from 2” to 3”, or from 3” to 4”). Also, be sure to run full port valves and tank fittings. Any restrictions in the suction line will hamper performance. You can only flow as fast as your smallest restriction.
- Most self-priming pumps are designed as internally bypassing, meaning a discharge bypass is not needed. However, it is recommended that you avoid slamming the discharge valve shut, as this can cause a water hammer effect, which can result in seal failure.
Pump is available with these variants:
300-6.5H: 3” polypropylene pump with GX-200 recoil start Honda, mounted on a base plate. Stainless fasteners and quality anti-seize used in assembly. Extra horsepower helps when pumping heavier liquid, when using longer discharge, or when bottom filling and fighting head pressure.
300-6.5H-ES: 3” polypropylene pump with GX-200 electric start Honda with recoil backup, mounted on a base plate. Stainless fasteners and quality anti-seize used in assembly. Extra horsepower helps when pumping heavier liquid, when using longer discharge, or when bottom filling and fighting head pressure.
300-6.51: 3” polypropylene pump with 6.5HP 1PH 208-230VAC Baldor TEFC electric motor, mounted on a base plate. Motor is single speed, and rotates at 3,450RPM. To “slow down” pumping, you may slightly close/throttle back the discharge valve. Stainless fasteners and quality anti-seize used in assembly. Extra horsepower helps when pumping heavier liquid, when using longer discharge, or when bottom filling and fighting head pressure.
300-6.53: 3” polypropylene pump with 6.5HP 3PH 208-230/460VAC Baldor TEFC electric motor, mounted on a base plate. Motor is single speed, and rotates at 3,450RPM. To “slow down” pumping, you may slightly close/throttle back the discharge valve. Stainless fasteners and quality anti-seize used in assembly. Extra horsepower helps when pumping heavier liquid, when using longer discharge, or when bottom filling and fighting head pressure.
300-HP: 3” polypropylene pump with .45 cubic inch hydraulic motor pedestal with flow control. Hydraulic motor has a max of 11GPM and 1,800PSI of hydraulic oil. Stainless fasteners and quality anti-seize used in assembly.
300-BP: 3” polypropylene pump with 3/4” shaft bearing pedestal for use with LoveJoys, Woods couplings, or pulley system. Pedestal ends in a bare shaft and does not include LoveJoy, Woods coupling, or pulley. Stainless fasteners and quality anti-seize used in assembly.
