Stainless Design Benefits

• SEALLESS - No Mechanical Seal, Magnetic Drives or
  Packing.
• SELF ADJUSTING - Maintains the delivery/ pressure
  performance over time with automatic
  disk/cylinder wear adjustment.
• DRY PRIME - Self priming and able to dry-run for
  up to 10 minutes. Capable of complete line
  stripping of suction and discharge pipes of
  residuals.
• 3A APPROVED - 3A and EHEDG (European Hygienic
  Equipment Design Group) certification, All wetted
  parts have a 0.8 Ra finish.
• CIP - Pump is designed to be flushed and cleaned
  in place without disassembly and has the
  capability to be completely drained.
• HIGH VOLUMETRIC EFFICIENCY - Pump is able to
  maintain a constant flow rate at a given
  viscosity throughout its pressure range.
• LOW SHEAR - Very careful handling of the product
  (Ultra low agitation and shear)

53
The General Application of C Series Pumps
54
C Series
Clean In Place
55
C Series
CIP Internal Action
Pressure is introduced to the back of the disc.
When pressure overcomes the spring the disc moves
away from the cylinder
56
C Series
This allows cleaning solutions to pass through
the pumping chamber
disc movement due to flush pressure
57
Clean In Place
Self Cleaning Or Cleaned by an External
Circulation Pump
The C Series Has a Low Pressure Drop Through the
Pump and May Not Need to Be Bypassed to CIP
Unlike Our Competitors The C Series has No Close
Clearances Smallest Clearance is 1/16 inch
58
CIP Continued

• The disk and cylinder react as a semi-open valve
  and allows a large flow to pass through the pump.
• CIP Example Flow at 40 GPM (10 m3/hr) with a
  pressure at suction side of 14 psi (1 bar)
  pressure loss in the pump 11.6 psi (.8 bar).

Blackmer will provide pump pressure drop data
for CIP Applications
