The reciprocating motion of the power end is uniformly transmitted to the diaphragm through hydraulic oil, causing the diaphragm to undergo reciprocating flexure. The diaphragm completely isolates the hydraulic system from the medium being transported. During the suction stroke, the volume of the medium chamber increases, the inlet valve opens while the outlet valve closes, and the medium is drawn in. During the discharge stroke, the volume of the medium chamber decreases, the outlet valve opens while the inlet valve closes, and the medium is discharged at high pressure under the push of the diaphragm.

Advantages & Highlights
Zero Leakage, Enhanced Safety
Diaphragm static seal ensures fully enclosed, leak-free operation, ideal for transporting high-risk, toxic, or high-purity media.
Stable Pressure, Accurate Flow
Hydraulically driven, delivering high and stable pressure with flow unaffected by outlet pressure fluctuations.
Strong Adaptability to Operating Conditions
Modular fluid end design enables the handling of high-viscosity, highly corrosive, solids-containing, easily crystallized, and shear-sensitive media.
Dual Protection, High Reliability
Double diaphragm with rupture alarm prevents media contamination and allows for maintenance switch without production interruption.
Efficient and Safe Operation
Complete with oil replenishment, venting, and overload protection, offering high volumetric efficiency and greater energy savings under high-pressure conditions.
Easy and Cost-Effective Maintenance
Fewer wearing parts, quick replacement—significantly reducing maintenance time and costs.
Application
Used for wastewater transportation and the transfer of corrosive and non-corrosive media in industries such as petroleum extraction, petrochemicals, electric power, and chemical processing. It can be configured as water injection pumps, pressure test pumps, acid pumps, alkali pumps, salt pumps, liquid ammonia pumps, ammonium carbamate pumps, polymer injection pumps, alcohol injection pumps, industrial pumps, agricultural pumps, high-temperature pumps, low-temperature pumps, etc.

Company Profile
Elephant Machinery specializes in reciprocating piston pumps, plunger pumps, and diaphragm pumps. Designed according to relevant national standards such as GB/T9234-2018 and GB/T7782-2020, as well as international standards such as AP1674, AP1675, and ISO13710:2004, these pumps can cover the flow and pressure requirements of various application fields and are widely used in oilfields and offshore oil platforms for water injection, polymer injection, CO2 injection, pressurization, pressure testing, cementing, and crude oil transportation; and in chemical applications involving strong acids, strong alkalis, and other chemicals. Transportation of corrosive or flammable and explosive media such as organic solvents; precise metering and transportation of pharmaceutical solutions, culture media, and solvents in pharmaceutical and bioprocessing; trenchless directional drilling; mining, geological exploration, deep well and geothermal drilling; transportation of tailings slurry, acid mine drainage, and electrolytes; hydraulic fracturing, roadway support, borehole sealing grouting, and tunnel drilling in coal mines; addition of acid-base neutralizing agents and flocculants in environmental protection and wastewater treatment; suction of sludge, chemical wastewater, and heavy metal waste liquid; and related applications in high pressure water jetting, food and beverage, etc.
By adding a diaphragm chamber to the reciprocating positive displacement pump, a large-sized diaphragm separates the pump's fluid end from the power end. This design achieves high flow rates, high working pressures, and minimal pulsation, enabling leak-free transportation of flammable, explosive, toxic, and hazardous liquids. The product complies with Chinese National Standard GB/T9234-2018, Mechanical Industry Standard JB/T8697-2014, and international API674 standard.
