Petrochemical Process Pump
Description of Petrochemical Process Pump
ASP5030, ASP5040 series are centrifugal chemical process pumps, which are developed based on the advanced pump manufacturing technologies domestic and abroad. They are designed to be horizontal single stage single suction radial split series pumps in line with the specifications in API610(the eighth version)and API682
They can be applied for the power of 50HZ and also 60HZ.
The pump follows the standard of ISO, API, GB, ASTM and JIS.
Different materials for wetted parts is available according to the liquid characteristic.
Application Area of Petrochemical Process Pump
Chemical industry, paper-making, pulp industry, sugar industry and the common process industry
Water supply plant, seawater desalination plant
Heating&air conditioning system
Environmental protection project
Shipping&marine industry, etc.
Working temperature: -80oC~450oC
Working pressure: (P): ASP5030up to 2.5MPa ASP5040up to 5.0MPa
Structural Characteristics of Petrochemical Process Pump
The balancing holes with wear-resistant rings are applied for the impeller to balance the axial force.
There are cooling or heating pipe joints for the packing box.
The packing seal, single mechanical seal or double mechanical seal can all be applied for the shaft seal. There is also auxiliary cooling, flushing or sealing liquid systems.
Taper-threads are applied for flushing and cooling joints for the casing, pump cover, intermediate bracket and sealing gland, which enhances its sealing ability and reliability for pipings.
The pumps with their outlet diameter more than 80mm. Their casings are designed to be of double volute to balance its radial force, which guarantees the bearing service time and the bending capability for the shaft at the shaft seal.
Closed impellers are applied for both ASP5030 and ASP5040 series pumps, which are characterized by their high adaptability, high efficiency and low NPSH etc.
Open impeller is applied to transmit the gas and liquid two-phase and the liquids with great solid particles concentration(max. Particles diameter 8mm, or 10% volume concentration).
Bearing structure and cooling: Bearing bracket is supported with a set of radial ball bearing and two sets of thrust ball bearings mounted in back-to-back. Bearings are lubed with oil rings or oil mist when specified. Bearing outside surface is furnished with cooling fin, which can be air cooling (T<120oC), fan cooling(T=120oC~260oC)and water cooling(T=260º C~450º C).
Q: Can your pumps mount Eff.1 motors
A: Currently, only on request though this will shortly be a CNBM standard.
Q: Are your pumps protected against dry running?
A: No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.
Q: How can I get trained on CNBM products?
A: Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.
Q: Are your pumps cheaper than those of your competitors?
A: CNBM aims to give its customers the highest standards of quality and service and delivery times, all at a reasonable price.
Q: Do you have self-priming pumps?
A: Yes, our product portfolio also includes two ranges of self-priming pumps: self-priming electric pumps and self-priming side channel pumps.
