Positive Displacement Pumps
Positive displacement pumps for controlled process transfer, metering and higher-viscosity liquids, including progressive cavity, rotary lobe, gear, screw, piston and diaphragm technologies.
Commercial & Industrial Positive Displacement Pumps Supply & Support
Positive displacement pumps move a fixed volume during each operating cycle, allowing flow to remain comparatively stable as system pressure changes.
Alton Pumps can help with pump selection, supply, installation, fault diagnosis, servicing and replacement for commercial and industrial process-transfer and metering applications.
The complete duty is reviewed before equipment is selected, including flow, total head, liquid characteristics, operating pattern, controls, pipework and electrical supply.
Correct
Pump Duty
Comes First
Typical applications include Viscous process liquids, Accurate metering and dosing, Food and hygienic transfer, Oils, chemicals and polymers, Low-shear product handling.
Because a positive displacement pump can generate significant pressure against a closed discharge, relief protection, control philosophy and pipework design must be assessed as part of the complete system.
For an initial review, send photographs of the pump and data plate together with the liquid type, pipe size, electrical supply, required flow, vertical lift and horizontal distance.
Duty-based selection
Pump choice based on flow, head, liquid, operating pattern and system conditions.
Repair or replacement advice
Clear assessment of repair viability, replacement options and whole-system causes.
Installation and commissioning
Mechanical, electrical and control checks completed before handover.
Planned and reactive support
Servicing, fault finding and responsive assistance for critical systems.
