In the Milton Roy hydraulic pump series, the M series and GM series have their own characteristics, and the selection should be based on specific application scenarios and needs.

The M series hydraulic pump has significant advantages in high pressure and large flow rate, with typical representatives such as the MBH series. The maximum flow rate of a single head can reach 2616L/H, and the maximum discharge pressure can reach 250bar. It is suitable for high-pressure scenarios such as petrochemical processes, hazardous chemical transportation, and offshore oil and gas lifting systems. Its design follows the API675 standard, using a ball joint crank connecting rod transmission mechanism, with built-in forced lubrication and oil bath lubrication systems to ensure the service life of moving parts; The hydraulic end can be equipped with insulation jacket, pressure type or electrolyte type double diaphragm leak detection and alarm device to meet the requirements of complex working conditions. For example, in the furnace treatment of the power industry, the MBH series can stably transport condensed water, circulating water, and wastewater, ensuring efficient system operation.

The GM series is known for its economy and ease of maintenance, and is suitable for medium and low voltage fields such as water treatment, environmental protection, and chemical industry. Its maximum flow rate is 500L/H, maximum pressure is 12Bar, steady-state accuracy is ± 2%, and it supports manual/automatic stroke adjustment and 4-20mA signal control. This series adopts a mechanically driven PTFE diaphragm, an eccentric mechanism design to make the pulse smaller, and an adjustable handle locking mechanism to reduce the failure rate; The casing, worm gear and other components are made of corrosion-resistant engineering plastics, and the oil bath lubrication design reduces maintenance frequency, with a maintenance cycle of up to 4000-8000 hours. For example, in sewage treatment, the GM series can accurately add coagulants to improve treatment efficiency.

When choosing, if it is necessary to handle high-pressure and high flow media, and there are high requirements for equipment life and safety, the MBH series is a better solution; If the focus is on economy, ease of operation, and application in medium and low voltage scenarios, the GM series is more cost-effective. In addition, it is necessary to consider the characteristics of the medium (such as corrosiveness, viscosity), environmental conditions (such as temperature, humidity), and control requirements (such as degree of automation) to match the optimal model.
