What Pumpflow does

Pumpflow Limited is a privately held UK pump engineering company founded in 2015 and headquartered in Manchester. The firm designs, manufactures, and tests bespoke rotodynamic pumps while operating the largest privately-owned independent pump testing facility in the UK, with flow capacity up to 10,000 m3/hr and power capability up to 4,000 kW. Its core product portfolio spans centrifugal and process pumps, VBX high head low flow pumps (API 610 12th Edition compliant), suspended bowl pumps, electro-submersible bowl pumps, hydropower pumps configured as turbines (5-200 kW), and the FS Range of NEN 8775-compliant fish-safe pumps for land drainage and flood control applications.

The company's underlying technology platform combines in-house FEA, CFD, and pump testing expertise with Q-Sight, a proprietary AI-powered condition monitoring system that uses supervised machine learning models trained on pump vibration and energy profiles to predict flow rates and detect anomalies without intrusive flow meters. All design, fabrication, machining, assembly, testing, and site installation work is performed in-house, with the exception of specialist alloy castings sourced from UK supply chain partners.

Pumpflow operates a project-based B2B enterprise sales motion targeting UK water and environmental utilities (Environment Agency, Internal Drainage Boards, drainage boards), civil engineering contractors (Balfour Beatty, Galliford Try), oil & gas end users and EPCs, OEMs requiring independent testing, and micro-hydropower developers. Revenue is derived from bespoke pump hardware sales, independent pump testing services, upgrade and retrofit contracts, re-engineering services, and a recurring subscription component from Q-Sight condition monitoring. Pricing is quote-based and project-specific, with no public pricing available. The firm is bootstrapped with no disclosed external funding rounds, no parent company, and operates as a founder/management-owned business.
