Description

DY-T2 Hydraulic Diaphragm Metering Pump Product Details

1. Product Overview

The DY-T2 hydraulic diaphragm metering pump is a high-precision safety quantitative conveying equipment specially designed for large-flow high-pressure working conditions, highly corrosive media and high-risk toxic & valuable fluids. Adopting an advanced closed hydraulic drive system, it completely solves the leakage pain points of traditional plunger pumps and mechanical diaphragm pumps. With a maximum flow of 23000L/H and a maximum pressure of 50MPa, it balances large-scale mass conveying and high-pressure precise proportioning.

It supports stepless flow adjustment during operation and shutdown with silent and compact structure. The unique no-load safe operation design allows stable operation without medium in the pump head, adapting to intermittent and unstable feeding conditions. Compatible with two-phase/three-phase standard and explosion-proof motors, it supports manual and automatic dual control modes. Optional PVC, PTFE, 304 and 316 stainless steel pump heads adapt to media from -30℃ to 100℃. The optional dual-diaphragm with rupture alarm device eliminates mixing risks of hazardous media and hydraulic oil, widely used in chemical, petrochemical, environmental protection and special industrial scenarios.

2. Core Product Advantages

Full Hydraulic Leak-proof Design, Safe for High-risk Media

The closed hydraulic drive structure separates the medium from mechanical transmission parts completely without dynamic seal leakage. It realizes zero leakage, zero pollution and zero liquid mixing, thoroughly avoiding medium loss, workshop pollution and safety accidents. It is the optimal equipment for closed conveying of flammable, explosive, toxic, radioactive and valuable rare fluids with far higher safety than ordinary metering pumps.

Large-flow & High-pressure Dual Adaptation, Efficient & Precise Mass Production

Breaking the limitations of low pressure and small flow of conventional diaphragm pumps, the DY-T2 series realizes stable synchronous output of 0–23000L/H ultra-large flow and 0–50MPa ultra-high pressure. The hydraulic uniform pressure transmission technology ensures stable metering accuracy without pressure attenuation and flow pulsation, meeting the dual demands of large-scale mass production efficiency and high-precision process proportioning.

No-load Safe Operation, Adaptable to Complex Intermittent Working Conditions

Equipped with exclusive no-load protection structure, it can operate safely for a long time even without medium in the pump head, avoiding burnout and diaphragm damage caused by dry running of ordinary pumps. It perfectly adapts to unstable feeding, intermittent feeding and frequent start-stop working conditions, greatly reducing failure rate and manual maintenance costs.

Full-range Material Modular Pump Head, Universal Media Compatibility

Four optional pump head materials match different media accurately: PVC for conventional clean water and weak acid-base media; PTFE for strong corrosion, solvent and easy-to-crystallize media; 304/316 stainless steel for high-temperature, clean and high-viscosity sanitary fluids. It fully adapts to clean water, acid-base corrosive liquid, suspension, volatile, crystallizable, flammable, explosive, toxic and radioactive special media.

Silent & Compact Structure, Minimal Maintenance

The optimized hydraulic damping structure ensures low vibration and silent operation. The compact and miniaturized design requires no complex installation foundation. The modular disassembly structure enables quick maintenance and parts replacement without professional tools, featuring low failure rate and long service life, suitable for 24-hour uninterrupted continuous mass production.

Dual-mode Flexible Flow Control

It supports on-site manual fine adjustment and full-automatic intelligent control. Flow calibration can be completed during operation or shutdown without production interruption and disassembly. The manual mode adapts to small-batch commissioning, while the automatic mode connects with industrial intelligent systems to realize unattended remote flow control, balancing flexible debugging and mass production efficiency.

Optional Dual-diaphragm Alarm, Double Protection for High-risk Conditions

For flammable, explosive, toxic and valuable high-risk media, the optional double-layer diaphragm structure and rupture alarm device provide double safety protection. The alarm triggers immediately once the inner diaphragm is damaged, effectively preventing medium-hydraulic oil mixing accidents and meeting strict safety production standards for special industries.

3. Working Principle

The DY-T2 hydraulic diaphragm metering pump operates on the hydraulic uniform pressure transmission isolation positive displacement principle. The motor drives the hydraulic system to transmit pressure evenly and stably through hydraulic oil, pushing the high-precision diaphragm to perform regular reciprocating deformation. Cooperating with the synchronous opening and closing of inlet and outlet one-way valves, it completes the whole process of medium negative pressure suction, high-pressure voltage stabilization and precise quantitative discharge.

The hydraulic full-range pressure transmission ensures uniform diaphragm stress and avoids fatigue damage. The medium is completely isolated by the diaphragm without contacting mechanical parts, eliminating leakage and pollution fundamentally. Matched with no-load protection and dual-diaphragm alarm system, it maintains long-term silent, stable and high-precision conveying under complex working conditions of wide temperature, corrosion and high risk.

5. Core Application Scenarios

Different from conventional small-flow precision pumps, the DY-T2 series focuses on large-flow high-pressure, high-risk medium and complex corrosion safe conveying, serving as a professional safety mass-production metering equipment for petrochemical, environmental protection and special industrial fields.

Petrochemical High-pressure Working Conditions: High-pressure large-flow chemical injection for oilfields, high-risk additive dosing for petrochemical reactors, and explosion-proof medium conveying for oil and gas exploitation. The 50MPa high-pressure resistance and dual-diaphragm protection ensure safe and stable operation under harsh oilfield processes.

Fine Chemical Corrosion Scenarios: Quantitative conveying of strong acid, strong alkali, strong solvent, volatile and crystallizable media. The PTFE anti-corrosion pump head resists severe corrosion, and the leak-proof structure avoids volatile medium leakage to ensure workshop safety.

Special High-risk Industrial Scenarios: Closed quantitative conveying of toxic, flammable, explosive, radioactive and valuable rare fluids. The optional diaphragm rupture alarm provides double safety protection to eliminate medium loss and potential safety hazards, adapting to strict processes of military, nuclear power and new special materials.

Large-scale Environmental Water Treatment: Mass dosing of acid-base neutralizers, flocculants and disinfectants for large sewage plants and industrial water treatment systems. The ultra-large flow meets high-load operation demands with low noise and simple maintenance for long-term continuous operation.

Pharmaceutical & Sanitary Light Industry: Precise proportioning and conveying of high-purity pharmaceutical liquids and food additives. The stainless steel pump head ensures no impurity precipitation or pollution, meeting sanitary-grade production standards.

Intermittent Non-standard Production: Suitable for production lines with unstable feeding and frequent start-stop. The no-load safe operation design eliminates manual on-duty requirements, reducing equipment failure and operation costs for flexible industrial production.
