BULLETIN PZ- 08 Series PZ / PZi / PZiG Pulse Metering Pumps US Patent #6,283,717 The Power of Intelligent Pumps Expands!
TYPE PZ (manual) TYPE PZi4 (automatic) Features TYPE PZi8 (programmable) MANUAL CONTROL TYPE • PZ Models (Speed only is adjustable from 15 to 300 SPM) Manual control Calibration function EXTERNAL PROGRAMMABLE INPUT INPUTS / OUTPUTS PZ PZD PZi4 PZi8 PZiG ៚ — — — — — ៚ ៚ ៚ ៚ • Enter desired flow directly in ml/min. — ៚ — ៚ ៚ • Calibrate pump flow to actual condition of chemical, pressure, viscosity, etc.
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.
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 pu
INCLUDED WITH EACH PUMP: Feed Verification 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 CONCENTRATION Acetic acid 50% RECOMMENDED TYPE • The flow checker is an oval gear flow meter which measures the pump output and transmits one pulse for each 1 ml of 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).
EXTERNAL DIMENSIONS Dimensions are shown in inches (mm). A *The mounting slots allow mounting from 3-7/16" (87) to 4-5/16" (110) centers.
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.
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 A *Input is connected to one PZi8 pump: Multiple PZi4 pumps would follow the pulse output of the PZi8 pump.
