Prochem PB Series Mixers

Prochem® PB Series Mixers combine the proven features of the MD Series with the advantages of a pillow block bearing design. You get truly efficient fluid processing plus maximum simplicity of maintenance. Instead of a bearing cartridge, PB Mixers are equipped with pillow block mounted inboard and outboard bearings that permit convenient servicing or replacement of bearings. All bearings, along with the stuffing box, are mounted and aligned in an integral fabricated steel base. No field alignment is required during installation or realignment necessary when bearings are replaced or packing is changed.

Horsepower and Speed Ranges

Standard PB Mixers are available from 1 hp to 300 hp with speeds from 160 rpm to 480 rpm. Mixer designs with enhanced operating capacity can be designed for applications with unique requirements.

Shafts

Heavy-duty, oversized shafts, the largest in the industry, are designed to handle up to 10 times the normal operating bending load at full torque. PB Mixers offer shaft sizes from 2" to 7".

Bearings

PB Mixers offer a minimum B-10 bearing life of 100,000 hours and feature pillow block mounted inboard and outboard bearings mounted and aligned on an integral fabricated steel base.

Unit Construction

All PB Mixers are completely assembled at our facility with all shaft, bearings and seals accurately aligned before shipment, No on-site alignment is required.

Housings & Mounts

Housings and motor mounts are fabricated from steel and can withstand loads several times that of typical application requirements. Two coats of polyurethane, catalyzed paint over a two-part epoxy primer protect against corrosion.

Tank Shut-Off Devices

An optional secondary shut-off seal prevents fluid leaking during routine bearing/seal maintenance so the tank does not have to be drained when servicing the mixer.

Belt Drives and Guards

Ultra VX belts and sheaves provide economical power transmission with shock-absorbing capability. Belt and shaft guards are made to OSHA standards. Guards on units with 3" or larger shafts contain access holes for adjusting belt tension. Drive systems are available for 1.3, 1.5 and 2.0 belt drive service factors.
