1 Series 500 dia-PUMP BULLETIN DP-1100-06 Series 500 dia-PUMP Innovative design, quality workmanship, long-term PUMP CO., Oil By-passTMstroke adjustment allowsbetter valve performance than variable linkagedesigns. The valve checks have extra time toseat even in heavy liquids since they are idleduring the by-pass portion of the suction and discharge It WorksHollow piston reciprocates within a rod fits into the piston. Note the frontof the piston, or nose , has a reduced liquid seal forms at where the full diameter of the piston contacts the the piston moves forward, oil by-passes overthe reduced nose, through port to the center ofthe piston and back to the gearbox. As the pistoncontinues forward, port is blocked by the tip ofthe metering rod stopping the by-pass. Oil is now pushed through port to the Series 500 dia-PUMP The only pumps with EZE-CLEANTMV alvesHydraulically balanced Teflon diaphragm eliminates diaphragmstress associated with mechani-cally flexed Cartridges can be removedfor cleaning withoutdisturbing the piping to the whilerunning through100% of range bymicrometer relief valve protects pump and spring providesback pressure when pumpingagainst low Refill mechanismoperates once per trainoperates in oil forextended the micrometer dial moves the metering rod and changes the pump capacity.

2 When the metering rod is moved in, the tip of the metering rod closes port sooner in the stroke allowing for less by-pass and more pumping , when the metering rod is moved out, the tip of the metering rodcloses port later in the stroke allowing more by-pass and less motion of the piston pushes and pulls the hydraulic fluid through port ,into and out of the diaphragm chamber. The action of the fluid pushes andpulls the diaphragm which, in turn, pushes and pulls chemical through port .The action of the check valves controls the direction of the liquid. 3 50/60 Hz, 110/220 V Explosion-proof (be certain to order propermotor for hazardous locations) Unit follows 4-20 mA or 1-5V signal Adjustable ratio signal to stroke 1:2 or 2:1 Direct (forward) or indirect (reverse)response to changing signal Manual override in event of instrumentsignal or power loss, a unique featureNote.

Refer to AR models found in BULLETIN DP-500E. Explosion-proof (be certain to order proper motor for hazardous locations) Unit follows 3-15 psi signal as standard; other signal ranges are available Direct (forward) or indirect (reverse) response to changing signal Local stroke position indicator on controllerNote: Can be mounted on both heads of duplex CONTROLThe flow rate of any Neptune dia-PUMP can be controlled automatically by a process instrument, or manually from a remote location, using the Electric Stroke Control to change stroke Neptune Electric Stroke Control is a one-piece, self-contained Electric Positioner mounted on the pump.

A metering pump should besized so the maximum expected flow rate is 80% to 85%of the pump capacity. The minimum capacity should neverbe planned less than 10% of the pump nameplate outdoor applications the pump motor should besheltered from direct sunlight to prevent overheating. The pump will operate in freezing temperature providedit runs continuously and provided the liquid beingpumped will not dust, which can ignite, as well as fumes or vaporswhen determining if a hazardous environment use a suction strainer 40 60 mesh to preventforeign matter from clogging the check suction and discharge isolation valves formaintenance.

10 Select large port, quick opening Column A suction draw down column is the most accurate and convenient method to measurepump Valve The internal relief valve furnished withthese pumps is to protect the pump. Provide an externalrelief valve to protect the system pressure valves are required when the system doesnot provide sufficient back pressure. Do not depend on aspring-loaded check valve when feeding from bulk tanksto a low-pressure application where the discharge isbelow the dampener is used when long discharge runs(between the pump and injection point) need dampeningto reduce water-hammer or pressure spikes caused byacceleration in the discharge Piping Keep the piping as short as possible,minimizing bends, elbows and other restrictions. Thesafest rule of thumb is to use piping one size largerthan the pump suction connection.
