PCM / PCM-SP Series

Pump casings with heavy wall thickness, machined from solid blocks of PP and PVDF. No metallic parts in contact with the pumped liquid. PCM and PCM-SP magnetically coupled are available with compact design. Self-priming models, series PCM-SP, are capable to lift corrosive liquid up to 5 mt without the need of a foot valve and with empty suction pipe. Ideally for underground tanks transferring and truck unloading.

Fields of Application

• Chemical plants
• Pharmaceutical
• Food processing
• Laboratories
• Transfer of solvents and alkalis
• Refrigerants

Materials

Techno-polymers: PP- PVDF

PTM / PTM-SP Series

PTM regenerative turbine pumps avoid oversized centrifugal with excessive by-pass and power requirements. Exotic alloy gear pumps designs, often result in rapid corrosion and wear, leading to costly replacements.                                                                                                                                               Oversized, high purity ceramic shaft, Silicon Carbide option. Self-balancing impeller eliminates thrust bearing wear. Handles up to 20% entrained gas.

Fields of Application

• Electroplating and galvanic systems
• Electronics systems
• Laboratories
• Filter units
• Water treatment (Chlorine dioxide)
• Transfer of strong acids

Materials

Techno-polymers: PP – PVDF

FEATURES

• Non-cantilevered shaft
• Hermetically sealed column
• Heavy duty column shaft with oversized ball bearings
• Exclusive solid machined thermoplastic casing and impeller components
• Oversized, high purity ceramic thrust bearings and shaft
• Modular impeller allows for modifying performances

MATERIALS OF COSTRUCTION AND PERFORMANCE SAME AS PCM PUMPS

SEAL-LESS API PUMPS

END SUCTION API 685

Seal-leas Pumps, are designed to meet critical nozzle loading and working pressure requirements of API 685 standards

FEATURES

• Over designed pump casings and baseplates
• Heavy duty containment housing for optimum safety
• External lubrication systems maintain highest pressure differential; allowing for deadheading and flow or pressure monitoring
• Dual back-pull-out (access hydraulic end or power frame)

SEAL-LESS MULTISTAGE BARREL API

Pumps are built for reliable, leak-proof operation in high discharge head applications.

FEATURES

• Between bearings support with no overhung loads
• Staggered volutes minimize residual radial loads
• Dynamically balanced, back-to-back impellers for minimal axial load
• TOP-TOP Suction – Discharge
• Heavy duty barrel casing
• Working temperature up to 250 °C
• Flow up to 200 m³/h
• Head up to 500 m

SPECIAL EXECUTIONS

SEAL-LESS VERTICAL PUMPS

NDMV                                                                                                                                                                                                    Seal-less Vertical Pumps, ensure leak-proof handling of corrosives. The heavy-duty shaft is supported by ball bearings without bushings to wear; shaft deflection is thereby eliminated          

FEATURES

• Non-cantilevered shaft
• Hermetically sealed column
• Heavy duty column shaft with oversized ball bearings
• Modular impeller allows for modifying performances
• Compact, high torque magnetic coupling with reduced mass

MATERIALS OF COSTRUCTION AND PERFORMANCE SAME AS NDM ISO 2858 PUMPS.

PCMV

Seal-less Vertical Pumps, ensure leak-proof handling of corrosives. The heavy-duty shaft is supported by ball bearings without bushings to wear; shaft deflection is thereby eliminated.                                                  PCMV Pumps are fabricated from solid thermoplastic material to resist internal or external corrosion. The hermetically sealed column is permanently isolated from corrosive liquid or fumes.
