Why it matters
The DPHC-F42 is a 4-chamber diaphragm pump with a brushless motor rated for 24/7 duty and about 20,000 hours. It moves 6 GPM with a 55 psi shut-off you can set between 40 and 80 psi; a built-in bypass reduces rapid cycling.
It self-primes with up to 9.8 ft of suction lift, survives up to 60 minutes of dry running, and includes a strainer and hose adapters.
