Dosing pumps

Product catalog summary

Overview: The document provides detailed technical information about electric dosing pumps manufactured by Hidroconta. These pumps are designed for precise fluid dosing, utilizing alternate piston movements to control flow rates.

Specifications: The pumps operate through an eccentric or crank-shaft rod system, with flow rates determined by piston strokes. Theoretical flow rate is calculated using the formula Q = S x C x Cl x 60 / 1000, where S is the piston cross-section, C is the piston height, and Cl is the piston movement per minute. Effective flow rate is typically 90% to 98% of the theoretical rate due to fluid infiltration through valves.

Operation: The operation involves two phases:

Suction Phase: The piston closes the discharge valve and opens the suction valve, allowing fluid to enter the chamber.
Compression Phase: The piston closes the suction valve and opens the discharge valve, pushing fluid into the discharge pipe.

Proper pipe diameter and minimal distance between the pump and fluid source are crucial for optimal performance.

Installation Recommendations: Pipes should have a diameter larger than the pump nozzle, especially for dense fluids, and fluid speed should not exceed 0.7 m/sec for viscosities up to 100 cp. The installation should avoid sharp angles and bends.

Technical Specifications: The document includes detailed dimensions and pressure ratings for various pump models, such as M 15, M 18, M 25, and M 35, with maximum pressures ranging from 6 to 30 bar and flow rates up to 1566 l/h. Materials used include AISI 316 for pump heads and Viton for piston seals.

Contact Information: Hidroconta is located in Murcia, Spain, with contact details provided for further inquiries.

DOSING PUMPS Hydrodynamic design The electric dosing pumps are alternate movement pumps. Their ﬂow rate is determined by the alternate movements of the piston, activated by an eccentric or by a crank-shaft rod system. For this alternating movement to be generated on the head when suctioning and discharging, a set of valves is installed that prevent the return of the ﬂuid, making the ﬂow rate intermittent and allowing the frequency to be determined by the number of piston strokes. The valves are spherical and closed by gravity. Theoretical ﬂow rate The theoretical ﬂow rate is equal to the volume...

DOSING PUMPS Operation 1. SUCTION PHASE: During this phase, the piston makes that valve close in the discharge position (due to its weight and the eventual pressure of the fluid), while it opens in the suction position due to the positive pressure generated during the suction phase. The fluid enters the chamber of the head and its volume is equal to that of the piston cylinder capacity. 2. COMPRESSION PHASE: During that phase, the piston makes the valve close in the suction position (as in the above case, due to its weight and the pressure exerted by the fluid); at the same time, the valve opens...
