Three-roller head, the same tube-only chemical path, and enough output that the timer usually sits well below 100%. Because the chemical only ever touches the tube, there is no seal, no diaphragm and no valve for chlorine or acid to attack — you replace a pinch tube instead of rebuilding a pump head.\u003c\/p\u003e\u003ch3\u003eFeatures and benefits\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePeristaltic design — chemical contacts the tube only, never the pump internals\u003c\/li\u003e\n\u003cli\u003eBuilt-in percentage timer with 0.6 to 900 second feed cycles\u003c\/li\u003e\n\u003cli\u003eUp to 38 GPD output at 30 PSI\u003c\/li\u003e\n\u003cli\u003eTool-free roller housing for fast pinch-tube changes\u003c\/li\u003e\n\u003cli\u003eChoice of 120V or 240V, cord or conduit entry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWho it's for\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eHigh-bather-load commercial pools\u003c\/li\u003e\n\u003cli\u003eAcid-feed duties on larger systems\u003c\/li\u003e\n\u003cli\u003eOperators who found a 12 GPD pump running near 100%\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eWhat's in the box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003ePro Series 300 metering pump\u003c\/li\u003e\n\u003cli\u003ePinch tube installed in the roller housing\u003c\/li\u003e\n\u003cli\u003eSuction and injection tubing\u003c\/li\u003e\n\u003cli\u003eInjection fitting and hose clamps\u003c\/li\u003e\n\u003cli\u003eOperating manual and wiring diagram\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eBefore you order\u003c\/h3\u003e\u003cp\u003eConfirm the supply voltage at the pump location and whether your conduit or cord entry is required by local code.
