Jabsco 14750-0003-P Nitrile Impeller Kit

Jabsco Profile B Nitrile Impeller Kit – 14750-0003-P / 6-147500003P

Product Description

The Jabsco 14750-0003-P is a compact eight-blade nitrile flexible impeller for compatible oil-transfer, bilge and general-purpose flexible-impeller pumps. Its nitrile construction is intended for pumping oily liquids, diesel-contaminated water and fluids that are less suitable for a standard neoprene impeller. It is also a documented replacement impeller for the older Jabsco Porta-Quick Oil Changer 17800-1000.

Product Compatibility

Documented compatibility includes:

• Pre-2004 Jabsco Porta-Quick Oil Changer 17800-1000
• Compatible Jabsco rubber flexible-impeller pumps requiring a Profile B impeller
• Bilge and transfer pumps handling oily or diesel-contaminated water
• Oil-changing and fluid-transfer equipment requiring an eight-blade, single-flat nitrile impeller measuring 1-1/4 × 15/32 inches.

Fitment Notice

Before ordering, confirm that the existing impeller requires:

• Eight blades
• 1-1/4-inch outside diameter
• 15/32-inch width
• 5/16-inch single-flat shaft
• Brass hub insert
• Profile B configuration
• Nitrile construction
• Jabsco 14750-0003-P specification

Do not confuse this part with Jabsco 14750-0001, which shares the same basic dimensions but uses neoprene instead of nitrile. The nitrile 0003 version is the correct choice where oil, diesel fuel or heavily contaminated water is present.

When This Part Needs Replacement

Replace the impeller when:

• Fluid-transfer performance decreases
• The pump becomes slow or difficult to prime
• The blades are cracked, hardened or permanently bent
• Blade tips are torn or missing
• The brass hub becomes loose
• The pump has operated dry
• The oil changer or transfer pump has been stored for a prolonged period
• Annual preventive maintenance is due

Flexible impellers should generally be inspected and replaced preventively rather than operated until complete failure. Jabsco guidance recommends replacement at least annually, or sooner where operating duty is severe.

Installation Notes

• Disconnect power to the pump before servicing.
• Remove the pump cover and old gasket or O-ring.
• Grip the impeller hub with a suitable removal tool or channel-lock pliers.
• Do not pry against the pump face with a screwdriver.
• Inspect the pump bore, cam, shaft and cover plate for wear.
• Remove any broken blade fragments from the pump and connected hoses.
• Apply glycerin or suitable impeller lubricant to the new impeller.
• Align the single-flat brass hub with the drive shaft.
• Install the replacement gasket and O-rings where applicable.
• Reassemble the pump and check for proper priming and leak-free operation.

Lubricating the new impeller assists installation and protects the blades during initial priming.

Parts Desk Insight

This impeller is visually similar to the neoprene 14750-0001, but the compound is the important difference. Choose the 14750-0003-P nitrile version for oil-changing equipment and pumps handling oily or diesel-contaminated fluids. Confirm the eight blades, compact Profile B dimensions and single-flat 5/16-inch hub before ordering.
