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.

2 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.

3 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.

4 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. 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.

5 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.

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).

7 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.
