ProMinent beta Metering Pumps

1 ProMinent beta 1 ProMinent beta Metering Pumps The Drive UnitPump housingConstructed of fiberglass -rein-forced PPE plastic, with a NEMA4x enclosure rating to protectagainst corrosion, dust and driveThe drive unit houses a short-stroke solenoid with a maximumstroke length of " ( mm).It is equipped with a noise sup-pressing mechanism for quietoperation and has only one movingpart, the on pulse action, eachpulse generates a magnetic field inthe solenoid coil. This magneticfield moves the armature the end of the armature is thediaphragm. The diaphragm pushesinto the dosing head cavity forcingchemical out of the dischargeThe beta pump series is a solenoid-driven, diaphragm-type Metering pump featuring the following: Microprocessor based Capacity range - gph ( - 32 L/h) Continuous stroke length adjustment from 0 to 100% 10-setting stroke frequency adjustment from 10 to 100% Maximum stroke rate: 180 spm Repeatability +/- 2% when used according to operatinginstructions Liquid end materials: PP, PVC, Acrylic, PTFE, SS Auto degassing liquid ends High viscosity liquid ends External access to options 12-24 VDC low voltage optionProMinent solenoid-driven meteringpumps consist of two main compo-nents: the pump drive unit and theliquid end.

2 The beta series offers twodrive (solenoid) sizes: beta/4 (BT4a)and beta/5 (BT5a). Operatingprinciples and options are identical,and both units offer maximumbackpressures up to 253 psig ( ). Capacity range for the beta/4 to 5 gph ( to 19 L/h); beta/5is to gph ( to 32 L/h).Feed rate is determined by strokelength and stroking rate: stroke lengthcan be varied from 0 to 100% with anadjustment ratio of 10:1. It is setmanually by the adjustment knobon the front of the rate can be adjusted in 10%increments between 10 and 100% viathe multifunction switch. This switch isalso used to select voltage-free On/Offexternal pulse contact, pump stop, ortest (for priming).CUTAWAY VIEW OF ProMinent BETA SOLENOID-DRIVEN Metering PUMP1 HOUSING2 LIQUID END3 DIAPHRAGM4 BACKPLATE5 SOLENOID6 SOLENOID COIL7 SOLENOID AXLE8 ARMATURE9 COVER10 STROKE ADJUSTMENTSCREW11 STROKE ADJUSTMENTAXLE12 STROKE ADJUSTMENTKNOB valve.

3 When the magnetic field isde-energized, a spring returns thearmature and diaphragm to theiroriginal position. This returnmovement draws chemical into thedosing head cavity through thesuction the event of a diaphragm rupture,the liquid end has a weep hole onthe bottom of the backplate todirect chemical out of the pump andaway from the solenoid. Anoptional diaphragm failure monitorcan be used to stop the pump andindicate a stroke-length adjusting mecha-nism is directly connected to thesolenoid. Adjustment results in anaccurate self-locking stroke lengthsetting. The DiaphragmThe diaphragm is constructed offabric-reinforced EPDM elastomerwith a plastic core and a PTFE-facing. It is chemically resistantagainst virtually all process fluidsand can be used over a widetemperature beta pump is designed with thenew-style convex diaphragm.

Performance isidentical whether operated on 50 Hzor 60 Hz power. The power cord EXTERNAL PANEL IN THE BASE OF THEPUMP ENABLES OPTIONAL RELAYS TO BEINSTALLED ON-SITE. The Liquid EndThe beta Metering pump liquid endsare available in five material versions: Polypropylene (PP) PVC (PC) Acrylic/PVC (NP) PTFE (TT) 316 Stainless steel (SS)Some liquid ends are interchangeablebetween the BT4a and BT5a (see tableon page 4).Options include a manual bleed valvefor easy priming and continuousbleeding of fluids that tend to off-gas(available with versions 1000-0713PP, NP and PC liquid ends).

5 Automatic degassing liquid ends areavailable for PP and NP versions(except 1000 and 0232). This new-style liquid end discharges from thecenter and degasses from the top toprevent air build-up in the viscosity PVDF liquid ends areavailable for pump versions 1005,0708, 0413, 0220, 1605, 1008, 0713,and 0420. Their Metering capacity is10-20% less than standard pumpversions and recommended viscosityis up to 3000 cPs. The HV liquid endsare not and discharge ports areequipped with double ball checkvalves for maximum repeatability.
