Applications:
Self-priming, single-suction hydraulic balanced twin screw pump especially suitable to deliver various lubricating fluids with high viscosity at medium or high temperature.
Technical Data:
• Pump Casing: Carbon steel/ stainless steel;
• Shaft: Alloy steel/stainless steel;
• Bearing Housing: Grey cast iron/carbon steel;
• Pump Nozzle Flange: GB/DIN/ANSI/GOST;
• Flange: DN20-DN300;
• Two casing constructions to select: 1. Side inlet, side outlet; 2. Side Inlet, up outlet.
Technical Features of FPDS2 Series Twin Screw Pumps:
• High-pressure design for the pump.
All standard pumps are designed to withstand pressure from 40 to 100 bar.
• Modular structural interchangeable design.
Pump's magnetic drive seal can be interchanged with mechanical seal structure. For convenient on-site inspection and maintenance without replacing the main parts.
• Designed for handling particulate medium.
Pump can be design without rolling bearings to prevent damage to rolling bearings caused by particulates or low-viscosity medium.
• Pump flow channel with no dead angles design.
Achieve thorough flushing function.
• Reserve design for fully heating jacket casing.
All pump types reserve space for a full heating jacket, allowing the installation of a fully heat casing without changing the installation space.
• Uniquely designed safety valve.
Built-in safety valve has a large volume and internal space, allowing for full recirculation without knocking. Same function as pipeline safety valve or flow control valve.
