CMP 27180-199-000 WhisperFlo Style Pump Basket

The CMP PUR AQUATRON, WHISPERFLO® Style Pump Basket (27180-199-000) is a precision-molded replacement strainer basket designed for Pentair WhisperFlo®–style pool pumps and compatible PUR AQUATRON pump housings. This basket installs inside the pump strainer pot and serves as the primary debris barrier, capturing leaves, insects, and larger contaminants before they can reach the impeller.

Over time, pump baskets can become brittle, cracked, or misshapen due to constant exposure to water chemistry and repeated cleaning. When this happens, debris may bypass the basket or restrict water flow, leading to poor circulation, increased noise, cavitation, and added stress on the pump motor. Replacing a worn basket with the correct WhisperFlo®-style fit helps restore proper hydraulic performance and protects internal pump components.

Manufactured by CMP, this basket is engineered to match the dimensions and flow characteristics of WhisperFlo®-style pumps, ensuring it seats correctly in the strainer housing and maintains consistent debris capture without collapsing under suction.

Why This Basket Matters

The pump basket plays a critical role in protecting your circulation system. Even small cracks or deformation can cause performance issues that escalate into costly repairs.

Why this matters:

• Prevents debris from entering and damaging the pump impeller

• Helps maintain proper water flow and circulation efficiency

• Reduces strain on the pump motor and seals

• Minimizes cavitation and air-related performance issues

• Supports quieter, smoother pump operation

Routine basket replacement is an inexpensive way to extend pump life and maintain reliable pool circulation.

Designed for WhisperFlo® Style Pumps

This basket is designed specifically for WhisperFlo®-style pump housings, including compatible PUR AQUATRON models. Proper fit is essential—incorrect or generic baskets can sit unevenly, reduce capacity, or allow debris to pass into the pump.

The open-grid design provides high debris capacity while allowing unrestricted water flow, helping the pump operate at its intended efficiency.

Durable Construction for Pool Use

CMP manufactures this basket from chemical-resistant, impact-resistant plastic formulated for long-term pool use. The material resists cracking, swelling, and deformation caused by chlorine, bromine, and fluctuating temperatures.

Its rigid structure maintains shape during operation and repeated cleaning, while the smooth rim allows for easy removal and proper seating in the pump housing.
