Hydraulic Gear Flow Dividers

The in- and outlet blocks of Jahns‘ Gear Flow Dividers are made from steel or aluminum and have integrated pressure relief valves for secondary loop protection, suction valves and measuring ports for each section.

Hydraulic Gear Flow Divider MTO (Aluminum Housing):

2 to 12 section divider. Flow Rate: 0.4 gal/min. to 16 gal/min per section. Working Pressure: up to 3625 psi. The chamber inlets are interconnected internally. Every second chamber has an inlet junction to enable connection according to flow rate and dynamic pressure. Version “A” has a combined pressure relief valve and pre-fill valve incorporated directly in the housing for each section. Version G – is without this valve.

Hydraulic Gear Flow Divider MTO (Cast Iron Housing):

2 to 12 section divider. Flow Rate: 3 gal/min. to 58 gal/min per section. Working Pressure: up to 3900 psi. Robust cast iron housing. Manifold block for end position damping, with pressure relief valve, pre-fill valve and test fittings for each section.

Hydraulic Gear Flow Divider HTO (High Pressure – Cast Iron Housing):

2 to 12 section divider. Flow Rate: 3 gal/min. to 37 gal/min per section. Working Pressure: up to 4600 psi. Robust cast iron housing. Optimized inner components: only two displacements cover the former four displacements.
