5 PZiA Automatic Flow Control Electronic Metering Pump Features Built-in calibration Maintains precise feed rate by correcting for changes in pressure/viscosity Precise batch injection Benefits PZiA Electronic Metering Pumps are the first in the world to feature an integrated automatic discharge volume control. Special circuitry allows onboard calibration of pump flow under actual process conditions. Each PZiA is furnished with a Flow Checker for feed verification and a constant pressure valve for the best possible accuracy. Once calibrated, the pump can be manually set or can be controlled by an analog signal. The pump then automatically adjusts by increasing or decreasing the stroking speed to maintain the precise flow rate regardless of changes in temperature, pressure, or viscosity. PZiA pump accuracy has been verified by KEMA. Constant Pressure Valve Flow Checker Stroke Adjustment Dial LCD Display (w/ backlight) 8-pin Signal Connector 4-pin Signal Connector (for flow checker) PZiA also performs precise batch injection. After calibration, a specific amount to be injected is entered on the electronic touch pad. Pump may be started manually or initiated by remote signal. The pump runs as long as necessary for the oval gear meter to measure the set amount and resets for the next command.

10 Neptune Series 500 dia-pump The only pumps with EZE-CLEAN TM Valves Variable Oil By-pass TM stroke adjustment allows better valve performance than variable linkage designs. The valve checks have extra time to seat even in heavy liquids since they are idle during the by-pass portion of the suction and discharge strokes. How It Works Hollow piston ❶ reciprocates within a cylinder. Metering rod ❷ fits into the piston. Note the front of the piston, or nose, has a reduced diameter. The liquid seal forms at ❸ where the full diameter of the piston contacts the cylinder. When the piston moves forward, oil by-passes over the reduced nose, through port ❹ to the center of the piston and back to the gearbox. As the piston continues forward, port ❹ is blocked by the tip of the metering rod ❷ stopping the by-pass. Oil is now pushed through port ❺ to the diaphragm. Internal relief valve protects pump and motor. Hydraulically balanced Teflon diaphragm eliminates diaphragm stress associated with mechanically flexed units. Antisiphon spring provides back pressure when pumping against low pressure. ❶ ❷ EZE-CLEAN TM Valves Cartridges can be removed for cleaning without disturbing the piping to the pump. Adjustable while running through 100% of range by micrometer dial. ❺ ❻ Power train operates in oil for extended service. Vent Refill mechanism operates once per stroke. Turning the micrometer dial moves the metering rod and changes the pump capacity. When the metering rod is moved in, the tip of the metering rod closes port ❹ sooner in the stroke allowing for less by-pass and more pumping action. Likewise, when the metering rod is moved out, the tip of the metering rod closes port ❹ later in the stroke allowing more by-pass and less pumping. The motion of the piston pushes and pulls the hydraulic fluid through port ❺, into and out of the diaphragm chamber. The action of the fluid pushes and pulls the diaphragm which, in turn, pushes and pulls chemical through port ❻. The action of the check valves controls the direction of the liquid. ❹ ❷ ❶ ❺ ❸ 2

11 Automatic Control Options SODIUM HYPOCHLORITE GAS BLEED Special head designed with an automatic air release valve to vent gas accumulation from chemicals that off gas such as sodium hypochlorite. Refer to AR models found in Bulletin DP-500E. PNEUMATIC STROKE CONTROL The flow rate of any Neptune dia-pump can be controlled by an instrument air signal when using the pneumatic stroke control to change stroke length. ELECTRIC STROKE CONTROL The 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 length. The Neptune Electric Stroke Control is a one-piece, self-contained Electric Positioner mounted on the pump. (See Bulletin ESC for complete details and ordering information.) 50/60 Hz, 110/220 V Explosion-proof (be certain to order proper motor 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 instrument signal or power loss, a unique feature Note: Can be added on only one head of duplex pumps. VARIABLE SPEED CONTROL 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 controller Note: Can be mounted on both heads of duplex pumps. The flow rate of any Neptune dia-pump can be controlled automatically by a process instrument using a variable speed drive to change pump stroke speed. Optional 56C frame motor flange adapter allows convenient mounting of any AC or DC variable speed motor control package. Note: Select pump with stroking speed sufficiently high that, at minimum speed, pump operates at 15spm minimum. 3

17 Double Diaphragm With Leak Detection 522-A-N3-DD Neptune offers a double diaphragm leak detection option for applications where contamination of the process fluid by the pump hydraulic fluid cannot be tolerated or where diaphragm failure must be sensed immediately. The Neptune double diaphragm design uses two dry coupled diaphragms. The area between the diaphragms is evacuated. Hydraulic pumping action is transmitted from one diaphragm to the other without the use of any intermediate fluids. The diaphragm condition is monitored by a pressure switch which can be wired to shut off the pump and/or sound a remote alarm. This design eliminates conductivity probes which could fail to detect the presence of oil or low conductivity liquids in the event of a diaphragm failure. The double diaphragm option DD is available on all Neptune Series 500, Series 500-A or Series 560 dia-pumps. Contact the factory for full specifications and applications information. PLANNING YOUR INSTALLATION Do not oversize the pump. A metering pump should be sized so the maximum expected flow rate is 80% to 85% of the pump capacity. The minimum capacity should never be planned less than 10% of the pump nameplate rating. For outdoor applications the pump motor should be sheltered from direct sunlight to prevent overheating. The pump will operate in freezing temperature provided it runs continuously and provided the liquid being pumped will not freeze. Consider dust, which can ignite, as well as fumes or vapors when determining if a hazardous environment exists. Always use a suction strainer mesh to prevent foreign matter from clogging the check valves. Provide suction and discharge isolation valves for maintenance. Select large port, quick opening valves. Calibration Column A suction draw down column is the most accurate and convenient method to measure pump performance. Relief Valve The internal relief valve furnished with these pumps is to protect the pump. Provide an external relief valve to protect the system piping. Back pressure valves are required when the system does not provide sufficient back pressure. Do not depend on a spring-loaded check valve when feeding from bulk tanks to a low-pressure application where the discharge is below the tank. Pulsation dampener is used when long discharge runs (between the pump and injection point) need dampening to reduce water-hammer or pressure spikes caused by acceleration in the discharge line. Suction Piping Keep the piping as short as possible, minimizing bends, elbows and other restrictions. The safest rule of thumb is to use piping one size larger than the pump suction connection. Piping may be the same size as pump suction connection for slow speed pumps used with low viscosity chemical. Feel free to contact the Neptune factory for application assistance.
