Series PZ / PZi / PZiG Pulse Metering Pumps The Power of Intelligent Pumps Expands!

MANUAL CONTROL EXTERNAL PROGRAMMABLE INPUT INPUTS / OUTPUTS • PZ Models (Speed only is adjustable from 15 to 300 SPM) Calibration function • Enter desired flow directly in ml/min. Manual control • Calibrate pump flow to actual condition of chemical, pressure, viscosity, etc. • PZD & PZi Models (Adjust speed 1 to 300 SPM plus stroke length Control input • External interlock (Examples: level switch, remote start, reset) Operation display • Indicates speed and status Signal output 4 8-pin connector • Pulse signal Frequency-divide 1/1 to 1/9999, Multiply 1 to 9999 (See pg.6) • Analog signal...

Type PZD/PZi-32/52 High Capacity Models PZD Series pumps offer higher capacities. These models feature an extra large keyboard and the injection rate can be entered directly in milliliters per minute. • Manual stroke length adjustment 20% to 100%. • Set points can be easily viewed on the LCD. The injection rate can be set three ways by direct entry of: – Stroke speed: 1 to 300 spm – Percentage: 1 to 100% High Capacity models are – Injection rate: ml/min. available in material codes • Pump head may be rotated to face in any of the three positions other than where the keypad and display are...

Variety of Liquid End Materials Standard Model: PVC (VFC/VEC) Stainless Steel Model (SS) ៓ Universal Model: PVDF ៑ (FFC/FEC/FTC) • For solvents and other chemicals where plastics are not suitable • For most chemicals and highly corrosive chemicals • General chemical applications • Valve seats and O-rings are available in Viton® or EPDM • Valve seats and O-rings are available in Viton®, EPDM or Teflon® • Built-in relief valve • Built-in relief valve Chlorine Model: ្ Acrylic (CL) • Transparent pump head allows visual check of valves • CL model with automatic air release mechanism • Reduced...

INCLUDED WITH EACH PUMP: Feed Verification Foot Valve Strainer* Back Pressure /Check Valve Injector with Quill* Back Pressure Injector Power Cord with 3-Prong Plug Signal Cable with Multi-Pin Connectors (one with PZi4 & two with PZi8 & PZiG models) *except some PZiG models (see page 4) MATERIAL SELECTION CHART PUMPING LIQUID (in alphabetical order) Acetic acid RECOMMENDED TYPE • The flow checker mounts directly to the discharge of PZ and PZi metering pumps. • The flow checker is an oval gear flow meter which measures the pump output and transmits one pulse for each 1 ml of flow. • Flow...

Advantages • Digital settings from 15 to 300 pulses per minute on PZ models and from 1 to 300 pulses per minute on PZi and PZD models • High stroking speed ensures more uniform distribution of chemical at low feed rates • Pump delivery is constant at any voltage from 94 to 264 VAC single phase and is not affected by voltage fluctuations • Outdoor use—pump is water and UV resistant. Equivalent to IEC specification IP65. Dust proof, wash down duty (with proper electrical connection). Cross Sectional view applies to PVC, Kynar and Type CL Heads; does not apply to Material Codes ARPZ, SS or any...

Programmable Models PZi8 & PZiG Control System Examples YOUR SYSTEM IS ENHANCED BY OUTSTANDING CONTROLLABILITY Proportional Flow Rate Control – Models PZi8 & PZiG Flow meter signals are received directly according to the flow rate of the main piping and the discharge volume is automatically controlled. Advantage This eliminates the need for control devices, which have been needed up until now, and reduces the cost of devices. Cost benefits: Digital panel meters, PID controllers and inverters are no longer required. Example: Any additive injected proportional to flow in a line Current system...

Multi-liquid Proportional Flow Rate Injection – Models PZi8* & PZiG Advantage 2-point Level Switch-based Control – Models PZi8 & PZiG Multiple PZiGs inject different chemicals according to preset values while calculating the signal from a single flow meter. This eliminates the need for a signal distributor. Flow meter (pulse/analog) PZiG system *Input is connected to one PZi8 pump: Multiple PZi4 pumps would follow the pulse output of the PZi8 pump. A 2-point level control enables output of an alarm at the liquid level “low limit” and stops pump operation at the “low-low limit.” PZiG system...
