Edson Air Powered Diaphragm Pumps are ideal for collection and transfer of liquid waste, dewatering, slurry, and filter applications. An externally mounted reciprocating air cylinder powers the single diaphragm at low air consumption rates. Open flow-through flapper valves and accurate, variable speed ceramic solenoid control make these pumps ideal for applications involving liquids with abrasive solids and high viscosities. Portable models are used for field applications with portable compressors.

In a fine example of "Yankee Ingenuity", Jacob Edson invented the diaphragm pump, and in 1859 established The Edson Corporation in Boston, Massachusetts to manufacture and sell his pump. He continued to invent a wide range of marine products which resulted in significant growth; and in the mid 1930"s the company moved to expanded facilities in New Bedford, MA. The Edson Corporation is now recognized as one of the oldest continuously operating businesses in Massachusetts and the United States.

Often used at marina"s instead of a macerator. For portable toilet and sewer contractors on a honey wagon. Edson Portable emergency manual bilge pump kits.

Edson Diaphragm Pumps are the most popular of all Edson Pumps due to their simplicity, reliability and convenience. They are an excellent choice for groundwater remediation, containment transfers, dewatering, oil and water separations, marina and ...

was only associated with large ocean racing and traditional sailboats The rapidly growing trend towards wheel steering has changed to include cruising and racing sailboats as small as 18 feet Many people once believed the only way toget theUfeelof a sailboat was with a tillerThe popularity of wheel steering as well as its practicality has shown even the most adamant tiller man that better feel and better boat control can be obtained with wheel steering Without the tiller sweeping theentire cockpit the crew can perform more functionally guests can relax more comfortably and shorthanded family sailing suddenly becomes simple Planning a steering system for a tiller conversion or an option on a new boat is not a casual matter and should be done with the utmost thought and consideration More time should go into the planning of acockpit than any other part of the boat this is where the crew spends the vast majority of their time whether the boat is for cruising or racing Moreover the cockpit is the base for handling sails as well as steering Thus in this one area of the boat comfort convenience performance and safety are all equally vital factors neglect even one and the pleasure of sailing is in ieooardvA major part of planning agood steering installation islocating thesteerer This must take location of the rudderpost winches main sheet and engine controls All must be located properly or moved to the appropriate location for a functional and comfortable cockpit The aft cockpit steering location is normally associated with h t e older traditional design where a worm gear type steerer to a rudderpost located in the aft end of the cock O p i t It is also the location used for the New Edson Rack and Pinion Steerer installed abovedeck directly toarudderpost located in thevery aft end of the cockpit or with atransom hung rudder The is often locatedwell aft in thecockpit in cruising and racing boats minimum distance 21 inches from the pedestal centerline to the aft cockpit bulkhead Theadvantageof any of theseaft steering installations is that the helmsman is well aft out of theway of crew members working winches From this position the helmsman sees all the action can cast off sheets or tail winches participate in cockpit conversation and has a complete view of the sails and rig In the midcockpit installation the helm is farther forward where the boat is wider so the helmsman can get more outboard instruments mounted in the cabin bulkhead can beeasily read the winches and cleats are more accessible to the helmsman whether they are forward or aft of the helm On a cruising boat this location clears the aft end of thecockpit forcrew members or guests not needed for handling sheets Neither the backstay nor main sheet need interfere with the helmsman standing behind the wheel and the helmsman has sufficient room to brace his feet without restriction With the helm in midcockpit winch location does become critical especially when installing wheel steer in in an exist in c o c k iwhere t winch locations are fixed concentrating both winches and helm in the middle of the cockpit can be most inconvenient for both helmsman and crew The forward cockpit installation places the helmsman close to the companionway under the protection of a dodger out of the way of winches and main sheet and in a wide part of the boat where head sails can be easily viewed fihoing the type of steerer is specifically covered on its I ppropriatepage of this catalog however each has certain which are best suited for a particular type boat Rack and Pinion Steering is most useful on boats from 16 to 40 feet where space under the cockpit floor is limited or for those small sailboats with transom hung rudders such as the trailerable models The inboard

plugged into these setups with a minimumamount of installation effort with the exception of building a cover over the steerer to serve as a helm seat Worm Gear Steering is often referred to as NonReversing meaning the feedback from the rudder will not normally turn the wheel when the helmsman lets go of the wheel These steerers are most often used on traditional boats with aft raked inboard rudders Because of the rake it is often impossible t o install a quadrant underthe cockpit floor This type of steerer is attached directly to the rudderpost above the cockpit floor at right angles to the rudderpost The steerer shaft may be fitted with a universal and an extra bearing to build in the exact wheel helm A wheel box must be built overthe steerer to serve as a helm seat This box can be kept as narrow as possibleso the helmsman can sit behindoralong side the wheel The box can have a flip up top to serve as a seat back for long watches at the wheel Engine controls can be located right on the sideof the helm seat within easy reach of the helmsman Despite the worm gear steerer being nonreversing there are always those boats with an excetional weather helm or oarticularlv hard

boats and bridge deck console type steering stations generally found on custom racing boats Bulkhead steerers can be purchased for very small boats using direct sprocket and chain drive as well as 2l and 3l geared reduction sprocket and chain steerers for very large commercial vessels such as fishing boats and tug boats Pedestal Steering is well suited for both midship cockpit and aft cockpit boats with inboard rudders as well as transom hung rudders This system requires space under the cockpit floor for mounting sheaves sheave bracket or Radial drive Steering System It offers maximum flexibility in that any number of sheaves may be mounted to route wire rope around engine spaces through aft cabins or around fuel tanks etcThe pedestal type system comprised of sprocket chain and wire rope can be used very efficiently for both cruising and racing boats up to 80 feet by varying the size of the steering wheel and the size of the quadrant toeffectively changethe poweroutput

seat and autopilot drives PullPull Steering is a new system offered by Edson as an alternative to a sheave and wire rope system This System can be used with either Bulkhead or Pedestal Steerers with inboard or outboard rudder boats It is most advantageous for MidShip Cockpit and Aft Cabin boats when routing the steering cables from the Center Cockpit to the rudderpost can become complicated The PullPull System uses standard Edson components in conjunction with flexible conduit housing 7 x 19 stainless steel wire rope Unlike pushpull cables such as those used on engine controls pullpull is always in tension The result is very positive steering control without the play and lost motion generally associated with a PushPull Cable Each steering section of the catalog shows a chart for

dummy rudderpost is going to be bolted to Bear in mind that this surface must be of sufficient strength as it must absorb all of the steering loads This platform must be 90 to the rudder on a plane where you wish to install the rudder lever Also note that the geared rack and pinion quadrant requires a minimum of 10 on each side of the dummy rudderpost to swing in This dimension will help in establishing the C dimensions Temporarily mount the dummy rudderpost and assemble the rack and pinion gear and housing Assemble the clevis the connecting rod and the rudder lever unit With C clamps attach the rudder lever unit to the rudder Now operate the steerer noting the rudder travel from side to side The location of the lever on the rudder either fore or aft or possibly even shimmed to starboard determines equal travel from side to side Take time with the positioning of this lever and be precise When you are satisfied secure all parts and install stops such as wooden blocks on each side of steerer to limit its travel to the desired arc Provisions for an emergency tiller should now be made if you do not already have oneCABLE SYSTEM FOR DOUBLE ENDERThe New Fig 345 Aft Mount Rack

extenders on Worm Steerers and Rack and Pinion installations where the existing rudderpost is too lowt z lfor all available sizes see p r i s pagesWorm steerer installations must be well designed and well thought out from all standpoints The basic system is mounted at 90 to the rudderpost and is rigid at this point The SelfAligning Bearing supplied with the gear must be well bolted down to a timber or strong moldment on a fiberglass design It is important to design in the basic features that make for a successful installation It is recommended that the top of the wheel the actual part you hold onto be 31 79cm to 33182cm up from the cockpit floor This will allow standing beside the wheel without reaching down to the wheel also sitting in back of the wheel or alongside it and have the wheel at a convenient height Essentially a Worm Steerer is a nonreversing system with little to no feel and is most commonly used on a longkeeled cruising design The steerer design features more turns pf the wheel from hard over to hard over than is normally designed into a wire type of pedestal systems The Worm Steerers would then not be recommended for a shortkeeled fast turning boat or one that does not track as well as the longkeeled boats The nonreversing feature will hold the wheel in place on most boats most of the time It will give or turn if the boat is hit by a large wave or the boat has an excessive helm due to basic design force of the wind or balance of the sails The gears are strong and relatively heavy as they must stand all of the strain of the rudder when transmitted to the gear The shaft extension or the wheel shaft itself can be easily 9pated to an AutoPilot by the addition of the necessary Jilot sprocket The choice of the location is one that will allow the sprocket chain to be led at right angles to the worm shaft directly to the AutoPilot motor box When ordering advise Edson of Rudderpost bore diameter Keyway size and Keyway position these will be machined by Edson If a special A length is required be sure to include itFIG 390 Edson Meteor Steerer With Worm Fore and Aft of Rudderpost Wt 128 lbs1585 k A 311FIG 380 Edson Robinson Worm Aft Steerer Wt 128

waterline the wheel can be angled at only 15 Edson feels the maximum angleof the wheel should be no more than 20 Likewise on near vertical rudderposts the same setup can be used to give the wheel some aft rake This angle is important as it will give the helmsman room for his knees while the top of the wheel is closer to his arms If in doubt as to steerer size or if the boat is very heavygo larger
