Constant Flow Rate Pumps - McMaster-Carr
网页Constant-Flow-Rate Pumps for Oil. A high -horsepower motor moves oil with a viscosity similar to SAE 60 motor oil. Also known as gear pumps, these produce a smooth flow of liquid to lubricate equipment and blend oils. Motor is open dripproof (ODP) for use in clean, dry, and well-ventilated environments.
Sparus™ Pump With Constant Flow Technology™ - Pentair …
网页Under typical operating conditions, Sparus Pump with Constant Flow Technology offers the highest water flow rate of any high performance pump—with the lowest electricity consumption. Thanks to its integrated on-board variable frequency drive, this pump automatically calculates and self-adjusts to provide the exact operational speed needed to ...

Control mode, constant flow pump | Grundfos
网页Constant flow is used in systems where there is a demand for a constant flow independent of the pressure loss, e.g. Chillers for air conditioning; Flow filters; Heat surfaces; Cooling surfaces; Grundfos constant flow pumps offering this control mode include speed-controlled circulator pumps and pumps with …
The essentials of pumping, pump speed and flow rate control …
网页2023年3月14日 · As illustrated in Figure 5, the power consumption of a pump remains constant when operating at its rated speed, despite variations in the flow rate. It can be seen from pump characteristic curves (both the pump curve and the system curve) that as the static head rises, the system curve rises as well since the system resistance also rises.
Constant Flow Rate - an overview | ScienceDirect Topics
网页Constant flow rate may be achieved either by using a separate pump with each bearing pad or by using a single pump and a separate constant flow rate valve with each bearing pocket (Figure 3.8). Either way, the overall bearing system is complex and expensive.
PD Pump Fundamentals, Design and Applications (Part One)
网页2009年2月5日 · PD pumps handle flow rates from less than 1-gpm to 15,000-gpm, and pressures from a few psi to 70,000-psi and higher. PD pumps, at constant speed, are constant flow rate devices, but centrifugal pumps are variable flow rate devices.
Design and development of a peristaltic pump for constant flow …
网页The “plus” pump allows for a percentage flow rate irregularity of under 5% with a higher average percentage flow rate than the previous geometries. This means that of all the liquid that could flow in the pipe without roller-related obstructions, more than 75% arrives at the discharge; this can be used as a machine efficiency term.
网页A constant flow micropump is a type of micropump that maintains constant flow rate of the working fluid during operation, and it has crucial applications such as medical diagnostics and as an essential part of precise analysis instruments [10].
