Shurflo # 8005-952-480 Diaphragm Pump with Bypass - 36 VDC

SHURflo 8000 Series diaphragm pumps are Self-priming, and feature Chemical-resistant materials. This pump has an internal bypass. Can run dry without damage. Shurflo 8000 Series internal bypass pumps are ideal for applications where an automatic demand switch is not desired. Pumps with bypass will continue to run without damage once the bypass pressure is reached. They incorporate a triple chamber design with Viton elastomers to withstand the toughest applications. Perfect for spot sprayers, foam markers and transfer applications where smooth, consistent flow is needed.

BYPASS : A bypass pump may be used in application that would normally induce frequent start/stop of the motor, and thereby create a potential for overheating. Models equipped with an internal bypass are designed to pump at high pressure while at low flow rates. Bypass models equipped with a switch may operate for several seconds even though the discharge side has been closed off. Models equipped with a bypass only will continue to run until power is turned OFF.
