IN­NO­VA­TIONS IN PUMP TECH­NOL­OGY

Marlin - - RUN&GUN - BY SAM WHITE

They might not be as sexy as a new cus­tom sport-fisher, but hav­ing good pumps and switches to move wa­ter ei­ther in or out of the boat is one vi­tally im­por­tant as­pect of any op­er­a­tion. Bilge pumps keep us afloat while livewell pumps keep the baits happy, and both are im­por­tant yet of­ten over­looked on­board sys­tems.

RISE OF THE SMART PUMP

Bilge pumps can be es­pe­cially trou­ble­some, since any­one pump­ing oil, fuel or other con­tam­i­nants over­board in cer­tain ar­eas like mari­nas and ma­rine sanc­tu­ar­ies can face sig­nif­i­cant fines for any vi­o­la­tions. With that in mind, Blue Guard In­no­va­tions has in­tro­duced a solid-state bilge-pump switch with oil- and fuel-de­tec­tion ca­pa­bil­ity. With no mov­ing parts or me­chan­i­cal float switches, the BG-One will au­to­mat­i­cally turn off the bilge pump when oil or fuel is de­tected, pre­vent­ing con­tam­i­nated over­board dis­charge. The BG-One can be in­stalled in any 12- or 24-volt power sup­ply and will source up to 20 amps to any DC-pow­ered bilge pump.

“Un­til now, there has not been a fail­safe sys­tem to mon­i­tor the ac­ci­den­tal spillage in ves­sels,” says Ken Franke, a re­tired mar­itime law en­force­ment of­fi­cer. “Blue Guard has de­vel­oped a ro­bust sen­sor with the BG-One that can pro­tect oceans and wa­ter­ways from oil and fuel spills, and can mit­i­gate ac­ci­den­tal spillage in ves­sels. This can pre­vent costly fines to boat own­ers and un­nec­es­sary con­tam­i­na­tion, plus ex­pen­sive cleanup by lo­cal au­thor­i­ties.”

The new bilge-pump switch has three pro­gram­mable modes of op­er­a­tion: Mode A (Ma­rina) turns the pump on when only wa­ter is de­tected, and off when oil or fuel is de­tected. Mode B (Ma­rine Sanc­tu­ary) turns the pump off and sounds an alarm, which re­quires power cy­cling of the de­vice to re­set the alarm. The Stan­dard mode op­er­ates as nor­mal, switch­ing the bilge pump on and off for any liq­uid. It’s a smart so­lu­tion to a trou­ble­some and po­ten­tially ex­pen­sive is­sue.

WA­TER, WA­TER EV­ERY­WHERE

Sea chests are de­signed to sup­ply large quan­ti­ties of wa­ter to feed a boat’s sys­tems. When used in con­junc­tion with

livewell pumps, a sea chest can solve myr­iad prob­lems. Best Ma­rine pro­vides en­gi­neered so­lu­tions for boat man­u­fac­tur­ers and own­ers, with a nearly bul­let­proof de­sign for dif­fer­ent types of hull de­signs and ap­pli­ca­tions.

“The big­gest chal­lenge we face these days are stepped hulls with dis­rup­tive wa­ter sup­plies at high speeds,” says Best Ma­rine owner Michael Pad­gett. Hooker Elec­tric re­cently com­mis­sioned Pad­gett to de­sign a sea chest that would be able to pro­vide the high vol­umes of wa­ter Hooker pumps are ca­pa­ble of han­dling, while elim­i­nat­ing cav­i­ta­tion, air lock and aer­a­tion, com­mon is­sues

with pumps on stepped-hull boats.

The Best Ma­rine sea chests are de­signed to keep the pumps up­right and pro­vide plenty of clean wa­ter to 2,500and 4,500-gal­lon-per-hour livewell pumps, as well as to feed salt­wa­ter wash­downs and var­i­ous other sys­tems. They are con­structed of 316L stain­less steel, which is then pas­sivized in a cit­ri­cacid bath and pow­der-coated to fully pro­tect it from the el­e­ments. Another crit­i­cal fea­ture is the pre­ci­sion tapped seal ring and neo­prene gas­ket, which al­lows the Best Ma­rine sea chests to be sealed with­out the use of caulk or other sealant. This makes pump changes or other main­te­nance much eas­ier. The chests can be de­signed for two to six Hooker Elec­tric pumps, of­fer­ing amaz­ing ver­sa­til­ity, re­dun­dancy and re­li­a­bil­ity for any boat’s livewell and wash­down re­quire­ments.

A sea chest can elim­i­nate prob­lems with ex­cess aer­a­tion and pump air lock in livewells and tuna tubes.
