SENTRY Pulsation Dampeners & Arrestors
Dampeners and Suppressors
remove hydraulic shock and vibration, enhancing all-around performance and reliability of fluid flow applications.
Positive Displacement (PD) pumps create pulsation and hydraulic shock due to the reciprocating nature of their stroking action, potentially damaging the entire pumping system.
BLACOH’s SENTRY Pulsation Dampeners & Surge Suppressors remove virtually all hydraulic shock, enhancing all-around performance and reliability of fluid flow in industrial and chemical transfer applications.
FDA compliant MATERIALS and easy to clean for sanitary or food applications.
Reduce pulsation, improve laminar flow, mitigate water hammer, shaking pipes, splashing, enhance pump performance and flow meter measurement.
SENTRY BENEFITS:
- Whether a piston, plunger, air diaphragm, peristaltic, gear, or diaphragm metering pump, a SENTRY Pulsation Dampener placed at the pump’s discharge will produce a near steady fluid flow up to 99% pulsation and vibration free
- Protects pipes, valves, fittings, meters, and in-line instrumentation from destructive pulsations, surges, cavitation, thermal expansion, and water hammer
- Creates steady and continuous flow when dosing, blending or proportioning additives
- Ensures accuracy, longevity, and repeatability of in-line meters
- Enables uniform application of material in spraying and coating systems
- Reduces product agitation, foaming, splashing and degradation of product
- Provides liquid energy storage for emergency valve closure and other equipment shutdown

Valve Hybride – Blacoh
l'avenir des systèmes de pompes doseuses. Présentation du premier amortisseur de pulsations combiné au monde et soupape de pression noire.
La nouvelle Hybrid Valve ™ de Blacoh, en attente de brevet, associe le contrôle constant du débit d'un amortisseur de pulsations et la régulation d'une vanne de contre-pression pour fournir les performances et les fonctionnalités des deux. Pourquoi installer et entretenir deux équipements lorsque le Hybrid Valve ™ fait la même chose, mais seulement mieux.
PERFORMANCE: LES CHIFFRES SONT INDÉNIABLE
La soupape hybride en instance de brevet a été conçue selon des principes éprouvés avec une conception de pointe pour des performances optimales et une efficacité maximale.
Dans un système de pompe doseuse, l'utilisation d'une soupape de contre-pression seule (orange) n'améliore en rien le débit de fluide. Lorsqu'il est mis en série avec un amortisseur de pulsations, le débit s'améliore de manière significative (rouge), mais les résultats ne peuvent toujours pas égaler les performances de la vanne hybride à construction unique pour le flux le plus stable (bleu).
Faites confiance aux experts en contrôle des fluides
L'emplacement et la proximité sont essentiels lors de l'installation d'amortisseurs de pulsations et de vannes de contre-pression dans tout système de pompage. Une soupape de surpression installée en série avec un amortisseur peut annuler l'effet d'amortissement si la soupape s'ouvre et se ferme avant que l'amortisseur ne puisse capter une impulsion complète. Cet effet d'ouverture rapide peut également générer trop de gain dans la soupape de contre-pression, ce qui entraîne une inefficacité et des bruits de claquement.
En combinant l’amortisseur et la soupape de surpression dans une seule unité technique, nous avons éliminé les problèmes les plus courants liés à l’installation pour un système plus efficace et simplifié.
VOIR LE HYBRIDE EN ACTION
Regardez notre directeur de l'ingénierie David McComb démontrer la Hybrid Valve ™ avec une pompe doseuse.
Il vous guidera à travers les performances de la pompe avec un amortisseur de pulsations seul, puis en série avec une soupape de contre-pression et enfin avec la nouvelle Hybrid Valve ™.
Comprendre les principes de la dynamique des fluides pour voir pourquoi la Hybrid Valve ™ offre les meilleures performances et donne à votre système la protection qu'il mérite.

SENTINEL Diaphragm Back Pressure Valves
Prevent siphoning and stabilize dosage rates with SENTINEL Diaphragm Back Pressure Valves
Diaphragm back pressure valves are designed to enhance the performance of pumping systems by applying a continuous back pressure to the system pump, while also acting as an anti-syphon valve. Robust construction ensures reliability in the rigorous service of municipal and industrial applications.
- Reliability and low cost
- Adjustable 5-150 psi for standard, 5-50 psi low pressure, or 50-350 psi high pressure
- Anti-siphon function
- Robust machined construction
- Vulcanized PTFE/EPDM diaphragm
- Full range of chemically resistant wetted materials
- Sizes from ¼” to 4” depending on model
Diaphragm back pressure valves apply positive discharge pressure to a metering pump system to prevent siphoning and eliminate varying dosage rates caused by fluctuating downstream pressure. The diaphragm is held against the valve seat by an internal spring. When the preset pressure is exceeded, the diaphragm is forced up and system fluid flows through the valve to the injection point. The valves are preset for 50 psi, however they are field adjustable from 5 to 150 psi, (optional up to 350 psi for high pressure) via the adjustment screw. Installation should be as close to the injection point as possible to prevent system line drainage, and it is most important that all pumping system equipment such as pulsation dampeners and pressure gauges are between the pump and back pressure valve

Sentinel Calibration Columns
Graduated Calibration Cylinders for Accurate Calibration of Chemical Metering Pumps
Blacoh SENTINEL Calibration Columns or Cylinders will enhance your feed systems by allowing verification of the flow rate of the feed pump.
- CNC machined ends
- Clear tube for easy GPH reading
- Sealed top
- Quick-off top for cleaning (optional)
- Loose top (optional)
- NSF-61 Approved Materials
Calibration Columns are installed on the suction side of the metering pump and are isolated with two valves installed with the cylinder.
The top of the cylinder is vented back to the supply tank or drain. The calibration cylinder is filled to the top mark then the valve from the tank is closed. Turning on the metering pump will draw down the liquid providing a simple means to verify the accuracy of the pump flow rate. USGPH (Gallons Per Hour) and ML are shown on the cylinder.
Blacoh SENTINEL Calibration Columns are critical to accurate determination of your system flow rate, either at start-up or following maintenance. They are offered in clear PVC or Borosilicate glass. Max cylinder pressure is 15psi.
