High-performance centrifugal chopper pumps

Gissing offers customers the Cri-Man PTH range, which wields immense power for slurry pumping systems. We provide the Cri-Man PTH100K (1:2.62) and Cri-Man PTH100KK (1:2.75) – both are up for the job, allowing you to spread quickly and effectively.

The Cri-Man PTH has a two-chrome steel blade chopping mechanism that works against a spiral conveyor fitted through a shear pin connected to the main impeller. With a speed of 1750 rpm, this is the first and only chopping system that operates at over 170 cuts per second!

The Cri-Man PTH range provides customers with high-performance secondary chopping through its incorporated high chromium steel serrated cutting flange.

Take a look at the Cri-Man PTH pump range, key performance details and specifications:

 

Cri-Man PTH100K:

  • Power Requirement (Hp): 150 – 190
  • Capacity (m3/h): 60 – 270
  • Capacity (l/min): 1,000 – 4,666
  • Head (m): 53 – 135
  • Bar: 5 – 13

 

Cri-Man PTH100KK:

  • Power Requirement (Hp): 175 – 200
  • Capacity (m3/h): 60 – 270
  • Capacity (l/min): 1,000 – 4,666
  • Head (m): 72 – 152
  • Bar: 7 – 15

 

Key Features:

  • Double chopping system meaning with speeds of 1750rp, the Cri-Man is the only chopping system that can operate at over 170 cuts per second.
  • Components undergo specific hardening treatments to ensure your new centrifugal chopper pump lasts.
  • Preserve the working life of the pump through thermal probe sensors immersed into the stator to prevent the electric motor from overheating.
  • Mechanical seals in silicon carbide and graphite-ceramic are supplied.
  • By request, a humidity probe can be installed within the oil chamber to prevent damage in the case of leakage.
  • The Cri-Man pumps are designed with high-efficiency hydraulics in mind. Gain up to 77% more efficiency with high chopping and anti-clogging performance.

Double Chopping System 1

The first chopping system consists of two chrome steel blades  fixed on the body inlet, acting in contrast to a spiral conveyor made from high grade cast iron and fitted to the motor shaft. Both materials undergo specific hardening treatments. With a speed of 1750 rpm, this is the first and only chopping system that operates at over 170 cuts per second!

Double Chopping System 2

The second chopping system consists of a shear cutting plate in special high grade cast iron that acts in contrast to the sharp profile impeller blades also in high grade cast iron. Both materials undergo specific hardening treatments.

Double mechanical seal

Mechanical seals in silicon carbide and graphite-ceramic.

Thermal probe sensors

Double thermal probes, immersed in the stator, prevent overheating of the electric motor and preserve its operating life.

Humidity probe (on request)

Humidity probe installed in the oil chamber to prevent damage in the case of leakage.

High efficiency hydraulics

Hydraulics designed to correlate high efficiency (up to 77%) with high chopping and anti-clogging performance. Data according to UNI EN ISO 9906 Standard.
