Diaphragm Pumps for Agriculture

JAECO AGRI-FRAM diaphragm pumps offer accurate metering, dependable performance, and hassle-free operation for your agricultural applications. 

The leak-proof design ensures accurate fertilizer, chemical, and difficult liquid metering. The hydraulic actuation extends pump life and allows for dry running without failure. 

We designed our agriculture pumps to last a very long time. Our rebuilding services can also restore older ones to peak performance.

Upgrade your irrigation, fertigation, and chemigation processes with JAECO AGRI-FRAM.

Robust construction helps to ensure a long service life.

Easy to Maintain

Design simplicity allows for easy maintenance.

Agricultural Diaphragm Pump Details

JAECO AGRI-FRAM pumps provide robust performance with a flow rate range of 0.86 GPH to 56 GPH and a pressure capacity of up to 1200 PSIG. Their hydraulically actuated design enables accurate metering, leak-proof operation, and the ability to run dry without damage.  

Choose between simplex or duplex models for tailored output, with field conversion options for added flexibility. These pumps also feature a heavy-duty gear system, a built-in relief valve, and a 10:1 turndown ratio for precise chemical or fertilizer delivery adjustments.

Agricultural Diaphragm Pump Models

JAECO AGRI-FRAM pumps come in simplex and duplex models to suit various agricultural needs.

Simplex & Duplex Agricultural Diaphragm Pumps

JAECO AGRI-FRAM diaphragm pumps handle diverse agricultural metering tasks with precision. Simplex models provide focused output for accurate chemical and fertilizer applications. For larger operations, duplex models offer increased flow capacity. Both designs leverage a hydraulically actuated system for reliable performance, leak-proof operation, and the ability to run dry for minimal downtime.

Motor Options

Belt-driven diaphragm metering pump

V-Belt Motor

Operates off-grid using alternative power sources (such as tractors) for remote flexibility.

Diaphragm metering pump with electric motor

12V DC Electric Motor

Ideal for remote job sites without access to reliable electrical power sources. This option is not very common.

Diaphragm metering pump with gas motor

Gasoline Motor

Enables pump operation in remote locations without an electrical power source.

Diaphragm metering pump with electric motor

Single or Three-phase Motor

Single-phase is suitable for standard power sources. Three-phase offers smoother motor operation and extended life.

Belt-driven diaphragm metering pump

Variable Speed Motor Drive

Offers precise, on-the-fly adjustments to pump output for enhanced chemical metering accuracy and efficiency.

Agricultural Diaphragm Pumps FAQ

Does the agricultural chemical come into contact with the hydraulic oil?

No. The JAECO AGRI-FRAM design employs separate chambers for the pumped liquid and the hydraulic oil. This design approach prevents any potential contamination.

What is the maximum flow rate of JAECO agricultural diaphragm pumps?

Our diaphragm pumps for agriculture have a maximum flow rate of 56 gallons per hour.

What is the maximum pressure your agricultural diaphragm pumps can handle?

We designed our pumps for pressures up to 1200 PSI to ensure reliable operation in various applications.
