• Specially designed for small burners.
• Two types of the pumps are available: 2-hole flange type (GFS-A) and set screw without flange type (GFS B). The cheap GFS-D without cut-off valve also available.
• The valve, having an innovative structure (patent pending), avoids troubles caused by rust and scale.
• The starting torque of 10 N･ｍ or less allows the use of energy saving motor.

• There are three models in terms of discharge capacity. Each model is subdivided, into nine models in total, depending on the shaft shape and other factors. Please contact us for the best selection of pumps to your application.
• The pumps are designed to deal with the Japanese kerosene that is poor in lubrication properties. The pumps are made of special materials featuring excellent durability, thereby ensuring a very long service life.

There are three models in terms of discharge capacity.
This pump has been developed to meet heavy oil pollution control requirements. The pump is designed in a two-stage structure to withstand 2.0 MPa high pressure even when Japanese kerosene is used under very unfavorable conditions. It is a large capacity pump for low viscosity boasting the world's highest reliability when Japanese kerosene is used.

VK model: for kerosene and heavy oil A
H model: for heavy oil B and C

• There are six models (202 model, 203 model, 204 model, 206 model, 208 model and 210 model) each for kerosene and heavy oil in terms of discharge capacity.
• The pumps have a two-stage design to withstand a high pressure (4.0 MPa for heavy oil and 2.0 MPa for kerosene) and to accommodate a large capacity (125-860 L/h for heavy oil and 60-760 L/h for kerosene).
• The pumps are designed to allow easy pressure adjustment using no tools.
• Because the material is different, it is not possible to share for kerosene and heavy oil.
