Product Description
PulsaPro 7440 Hydraulic Diaphragm Metering Pump
The PulsaPro 7440 Hydraulic Diaphragm Metering Pump provides accurate chemical delivery for demanding high-flow and high-pressure processes. Moreover, it combines hydraulic diaphragm technology with robust industrial construction.
The pump delivers flows up to 4,160 litres per hour and pressures up to 220 bar. Therefore, it suits critical chemical-injection duties across Indian oil and gas, petrochemical, power-generation and water-treatment facilities.
Manual or automatic XAE capacity control provides flexible operation. In addition, the pump delivers linear flow adjustment with metering accuracy within ±0.5%.
High-Pressure Chemical Metering
The PulsaPro 7440 uses a hydraulically actuated diaphragm to separate the process chemical from the drive system.
As the piston moves, hydraulic oil transfers motion to the diaphragm. Consequently, the pump delivers a controlled chemical volume while preventing process liquid from entering the gearbox.
This design combines the efficiency of a reciprocating plunger pump with the containment benefits of a diaphragm seal. As a result, it supports accurate and leak-resistant chemical dosing.

Flow and Pressure Performance
The PulsaPro 7440 supports demanding process conditions:
- Maximum flow: 1,098 gallons per hour
- Maximum metric flow: 4,160 litres per hour
- Maximum pressure: 3,200 PSI
- Maximum metric pressure: 220 bar
- Steady-state accuracy: ±0.5% of set point
- Repeatability: ±0.5% of rated capacity
- Linearity: ±0.5% over a 10:1 range
- Maximum fluid temperature: 121°C
- Viscosity capability: Up to 1,000 cP
- Required net positive inlet pressure: 0.2 bar
However, final performance depends on the selected pump head, motor, valves and process configuration. Therefore, users should confirm the complete operating conditions before ordering.
Manual and Automatic Capacity Control
The full-motion stroke mechanism provides accurate capacity adjustment.
Manual Stroke Control
Manual control allows operators to adjust pump output locally. Therefore, it suits processes with stable chemical-feed requirements.
Automatic XAE Control
The optional XAE controller adjusts stroke length automatically. As a result, the pump can respond to a process signal or plant-control system.
Moreover, XAE control supports remote operation and improved process automation.
Hydraulic Diagnostic Window
The hydraulic diagnostic window allows operators to inspect oil condition and pump operation visually.
Consequently, maintenance teams can identify potential hydraulic issues more quickly. This feature may also reduce troubleshooting time and unnecessary disassembly.
Overpressure and Diaphragm Protection
An externally adjustable bypass valve protects the pump from excessive system pressure. Therefore, operators can adapt the protection setting to changing process requirements.
In addition, the high-performance protection valve safeguards the diaphragm during starved-suction conditions. As a result, it can reduce diaphragm damage, downtime and maintenance costs.
Push-to-Purge Hydraulic System
Air trapped in the hydraulic system can reduce pump efficiency.
The push-to-purge feature allows operators to remove hydraulic air when required. Consequently, the pump can restore efficient operation without a lengthy maintenance procedure.
Pump-Head and Diaphragm Options
Available Pump-Head Materials
- 316 stainless steel
- PVC
- Monel
- Alloy 20
- Hastelloy C
- PVDF
Available Diaphragm Options
- Single flat PTFE diaphragm
